| A | B |
|---|
| multicellular | many-celled |
| eukaryote | having a "true" nucleus with DNA enclosed in a membrane and other membrane-bound organelles |
| cellulose | complex carbohydrate making up cell walls in plants |
| photosynthesis | process in which carbon dioxide and water in the presence of sunlight with chlorophyll are used to produce glucose and oxygen |
| chlorophyll a and b | green pigments in plants used to capture sunlight for photosynthesis |
| diploid (2N) | two sets of a genome; in the sporophyte generation of plants |
| haploid (N) | one complete set of chromosomes; in the gametophyte generation of plants |
| alternation of generations | two phases in the life cycle of plants whereby mitosis and meiosis alternate to produce spores and gametes, respectively |
| eggs | female gamete |
| sperm | male gamete |
| what plants need to survive | sunlight, water and minerals, gas exchange, transport of water and nutrients throughout the plant body |
| main features for how plants are classified | water-conducting tissue, seeds, flowers |
| produce flowers | flowering plants (angiosperms) |
| produce seeds in cones | conifers or cone-bearing plants (gymnosperms) |
| produce spores in dominant generation | spore-bearing or sporophyte plants (ferns and relatives) |
| lack water-conducting (vascular) tissue | mosses and their relatives (bryophytes) |
