Card Set Information
plant and animal terminology for the ASVAB test
- the basic unit of life.
- human body over 75 trillion cells.
- one of the type of cells.
membrane-bound structures inside the cell.
- one of two types of cell.
- has internal membrane-bound structure inside the cell.
: protists, fungi, plans, and animals.
Cells are made of several different parts:
, and a large amount of mass called
- is the dictator of the cell
- it determines what goes into or out of the cell.
- a gelatin-like material that fills the cell.
- specialized parts that move around the cell and perform functions that are necessary of life.
: cell nucleus, vacuoles, and mitochondria
- membrane that contains the cell's hereditary information and controls the cell's growth and reproduction.
- the most prominent organelle in the cell.
that are made up of DNA.
- the storage containers of the cell.
- may store waste until it is eliminated or food unit it is needed.
- energy for the cell is produced by
through a process called
The basic difference between plant and animal
plant cells have cell walls and chloroplasts, and animal cells do not.
- only in plant.
- gice the cell a firmer shape and support.
- organelles in plant cell.
- these contain chlorophyll, which uses the process of
to make food for the plant cells.
Carbon Dioxide + Water => Glucose + Oxygen
DNA (deoxyribonucleic Acid)
- determines how one looks and how one functions.
- DNA molecule consists of two long strands that form a double helix.
- DNA has a sugar component, a phosphate component, and four different bases -
Adenine is always pair with
Cytosine is always pair with
- the instruction for the appearance and function of the new organism are contained in units called
- which are parts of DNA.
- one of two reasons for the cell division.
- when cells are repacing themselves beucase they are old or worn-out.
- for cell division
- nucleus divides once
- number of cells formed = 2
- chromosomes in each new cell = 46
- one of two reasons for cell division.
- takes place with sex cell formation.
- cells with only 23 chromosomes are formed so that when an egg and a sperm join up, they have the full set of 46 chromosomes.
- for sex cell formation
- nucleus divides twice
- number of cells formed = 4
- chromosomes in each new cell =23
- a piece of hereditary material surrounded by a protein coating.
- do not have a nucleus or other organelles.
- need host in order to reproduce and function.
- cannot generate or store energy, but take their energy from the host.
- all viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat.
Scientist use an ordered ______ (classification system) to classify living things.
The levels within Taxonomy (descending order)
All life is categorized into five kingdoms
- one-celled or a colony of cells, decomposes and parasites, move in water, and both producers and consumers.
: bacteria, blue green algae
- one celled or multicelled, absorb food , move with flagella, both asexual and sexual reproduction, producers and consumers.
: plankton, algae, amoeba, protozoans
- one-celled and multicelled, decomposes, parasites, absorb food, asexual, reproduction and budding, consumers.
: mushrooms, molds, mildew, yeast, fungi
- multicelled, photosynthesis, mostly producers
: angiosperms, gymnosperms, mosses, ferns
- multicelled, parasites, prey, both asexual and sexual reproduction, consumers.
: sponges, worms, insects, starfish, mammals, fish, amphibians, reptiles, birds, gorilla, humans.
Human beings can be categorized according to taxonomy in this way:
- kingdom -> animalia
- phylum/division -> chordates
- class -> mammals
- order -> primates
- family -> hominidae
- genus -> homo
- species -> sapiens
- Scientific Names -> Homo sapiens
- use an outside energy source, such as sunlight, to produce energy.
- most producers have chlorophyll (plant, but not all)
- cannot make their own energy; to live, they need to eat other organisms
- scientific study of plants.
- plants transport water from the roots to the stems and to the leaves by means of tubelike structures.
- plants absorb water only through their surfaces.
- seeds store food for the growing plant; the part of the seed that stores the food.
- seeds have one cotyledon.
- seeds have two and more cotyledon.
- plants go through their entire life cycle, for germination through seed production to death, in one growing season.
: corn, zinnias, beans, marigolds, and mums all have to be plant each year.
- plan have life cycle of two years.
: onions, raspberries, hollyhocks, and carrots.
- plant live for many years.
- parts of the plant may die back during the winter, but the plant will grow back in the spring.
- plant, including shrubs and trees, lose their leaves in the winter.
: maple and oak
- plant keep their leaves or needles throughout the year, sometimes shedding only old leaves or needles that are more than two years old.
- absorbing nutrients and water, anchoring the plant into the soil, holding up the stem and leaves, and storing food.
There are two types or root systems:
system and a
- has one fat or sturdy root, with just a few branching roots.
: carrots, radishes, and parsnips.
Fibrous root system
- has many branched roots.
- main trunk of a plant
- major functions of the stem is to move water, nutrients, and food through the plant. (using vascular system)
- move food from the roots through the stem to the leaves.
- move minerals and water.
- major job is to make food for the plant.
- a protective layer on leaves.
- it reduces the evaporation of the water from the plant and helps to protect the plant from disease-causing organisms.
- a tiny opening on leaves.
- it enable the plant to take in carbon dioxide and release oxygen into the atmosphere.
- cover the stomata openings and regulate the exchange of water vapor, oxygen, and carbon dioxide into and out of the stoma
- the main job of flowers is sexual reproduction or seed production.
- is the female portion of the flowers
- it includes the
, the surface that captures and holds
, the area between the stigma and the
- is the make portion of the flower.
- it includes the filament that holds the
- where the pollen is formed and released.
- plants respond either positively or negatively to various stimuli (gravity, light, or touch).
- plants response to gravity.
- plants respond to light.
- animals are generally categorized in terms of whether or not they have
- animal that have backbone.
- animal do not have backbone.
- invertebrates, like snails, have soft bodies, but have developed a hard shell for protection.
- can live in water or on land
: snails, clams, mussels, and squid.
- invertebrates have tough coatings made of chitin on the outside of their bodies.
- they also have joined legs and segmented body.
- aka. arthopods.
: centipedes, millipedes, insect, shrimp, lobsters, and crabs.
- animals that primarily eat plants.
- animal that feed mostly on meat.
- animal (human) eat both plants and meat.
- teeth are designed for grinding tough plant fibers.
- if animal's body temperature follows or matches the external temperature around it.
: fish, amphibians, and reptiles.
- animal can control their body temperature.
: only bird and mammals.
- mammals use their hair, skin, or fur to adapt to temperature changes.
- the sum of all the places on Earth where life can exist.
- collection of all the living creatures and nonliving features or conditions in a particular environment.
- the study of ecosystem - the interactions between and among these living creatures and nonliving features.
- is the variety of life forms that exist.
- biodiversity tends to increase as one approaches the equator.
- warmer weather tends to support biodiversity.
- resulting from sending carbon dioxide into the atmosphere can raise temperatures and affect biodiversity.
- the thinning of the ozone layer in the atmosphere can increase the amount of ultraviolet radiation (UV) the reaches Earth.
