has a lot of variability in both flower and vegetative structure; can be woody or herbaceous
1) Can vary in size, location, flowers, nutrition, stems, roots, petal number, longevity, leaf arrangement
What is the importance of monocots?
a. They dominate everything. For example, monocots are the base of civilization since grasses are monocots and are greatly relied on for sustenance. Examples are rice, wheat, and corn.
Explain the four flower parts
From outside in, it is the sepals, petals, stamens, and pistils. They get closer inward and are higher up from the previous. Having all four means the plant is complete; lacking one or more is incomplete. They can be perfect if they have both stamens and pistils; or, they can be imperfect (staminate or pistillate) if they lack one of the parts. All of these are modified leaves.
The very tip of stem where the flower attaches is called the ___. The flower stalk itself is called the __. What happens as you go the (first answer)?
a. ANSWER: RECEPTACLE; PEDUNCLE; FOUR RINGS GET CLOSER TO THE CENTER OF THE PLANT
4) What is at the cross-section of an anther?
a. The pollen sacs are in the middle and are going to produce pollen; there is a tapetum that contains the nutritive cells
Explain the pistils.
There can be simple pistils, which are made of a single carpel. The ovule forms on the surface and then is enclosed so that the ovules are inside. There are compound pistils, which are made of multiple carpels fused tgether. In a simple pistil, the seeds are in a single carpel.
What does a fruit form from?
a. A fruit forms from a flower. Only flowers produce true fruits.
7) Explain dry fruits.
a. Fruits that can produce from a simple or compound pistil; can have seeds; not eaten; can be dehiscent (opens at matury) or indehiscent (remains closed at maturity)
Monocot vs Dicots
Two cotyledons; give rise to a root and shoot system with the radicle (becomes the root) and the hypocotyl, which becomes the shoot
Monocots versus Dicot
Food stored around embryo and the cotyledon functions to absorb it as the seed develops
Food stored in cotyledon
Monocots versus Dicots
In general, they have fibrous roots
In general, they have taproots
Monocots versus Dicots
- Petals are multiples of three
- Petals are multiples of four or five
