Compare characteristics of plants and green alga

Cell walls are composed of cellulose Cell division that includes the formation of a cell plate They have the same chlorophyll used in photosynthesis Food stored as a starch

Name the adaptations of plants to land environments

Cuticle,stomata, reproductive strategies, vascular tissues, and seeds

a waxy fatty layer it prevents water loss it prevents microorganisms entering the plants.

it allows exchanges of gases(oxygen and allows carbon dioxide goes in) are usually on the underside of leaves open more at night time

Describe Vascular Tissues

specialized transport tissues it transports water and food allowing the plants to grow tall they provide support and structure Nonvascular plant move food and water by osmosis and diffusion and are short plants.

Describe Reproductive Stategies

are some land plants that use spores to reproduce but they are water dependent Seeds

they contain an embryo, nutrients for the embryo to grow, and a seed coat for protection seeds will not grow until favorable conditions exist.

Explain alternation of generations of plants Gametophytes

t produces gametes( are half floyd cells that are either sperm or egg) when the sperm fertilizes the egg a diploid zygote forms that undergoes mitosis forming a sporophyte generation

Explain alternation of generations of plants Gametophytes Part 2

the sporophyte generation produces spores that can grown to form the next generation gametophyte generation. in most cases the sporophyte generation is dominant.

Identify the structures of nonvascular plants

They are small plants they usually live in very damp shady areas Because of the lack of vascular tissue water and nutrients move by osmosis and diffusion
