-
____________ make their own food, while ____________ eat other organisms.
- 1. Autotrophs
- 2.Heterotrophs
-
What is photosynthesis?
It is carried out by plants, algea and blue-green bacteria( autotrohs). It takes the radiant energy of the sun and puts it in the bonds of sugar molecules. PHOTOSYNTHESIS occurs mostly in the CHLOROPLAST of PLANT CELLS.
-
What do plants have?
Stomates
-
What is a stomate?
it's small holes in their leaves that let them exchange the gasses used in photosynthesis.
-
Guard Cells P.S. they don't guard the cell!!!!!!!!!

-
Respiration
Organisms get energy by breaking the bonds of sugar molecules. The released energy is used to make a molecule of ATP, which gives all organisms their energy. -Takes place in the mitochondria
-
Aerobic Respiration
requires oxygen, and more ATP(energy) for a molecule of sugar than anaerobic (no oxygen) respiration.
-
What is diffusion?
movent of molecules from high concentration to low concentration which requires no energy( passive transport)
-
Active Transport
requires the use of energy, usually moving molecules from a low to high concentration( against the flow of diffusion)
-
What is osmosis?
thediffusion of water into or out of the cell.
-

- 1. Nervous System
- 2. Endocrine System
