 all plants are _____ ______ and are ________ (how do they attain food) | multicellular eukaryotes; autotrophs |
| a complex carbohydrate | cellulose |
| complex cell walls are composed of _________ | cellulose |
| what are the 4 organs of a plant | leaf, root, seed, stem |
| what takes place in the leaf | photsynthesis |
| what does the root do | absorb water and minerals from the soil |
| what does a stem do | transports food, water, and other materials to and fro in the plant |
| what does a seed contain | a plant embryo along with a food supply |
| contains tubelike elongated cells through which water, food, and materials are transported | vascular tissue |
| water and nutrients travel from one cell to another by osmosis and diffusion | nonvascular plants |
| how many stages do the life cycles of plants have | two |
| what are the two stages in the life cycles of plants called | generations |
| the diploid stage is called the ________ | sporophyte generation |
| the gametophyte generation produces what | male and female gametes that can unite and begin a new sporophyte generation |
| in nonvascular plants, the sporophyte and gametophyte generations usually... | remain attached (sporophyte smaller than gametophyte) |
| in nonvascular plants the sporophyte is... | dependent on the gametophyte |
| in vascular plants the sporophyte is... | independent and dominant |
| plants that do not use seeds to reproduce use... | spores |
| hard walled reproductive cells produced by meiosis | spores |
| name six non seed plants | mosses, liverworts, hornworts, club mosses, horsetails, ferns |
| nonseed nonvascular plants that live in cool moist enviorments and ussualy not taller than a few centimeters | mosses, liverworts, hornworts |
| nonseed vascular plants found in moist enviornments only a few centimeters tall | club mosses |
| nonseed vascular plants common in areas with damp soil relatively small | horsetails |
| diverse group of nonseed vascular plants that have leaves called fronds and found in a variety of habitats | ferns |
| fronds grow from an underground steam called | rhizome |
| seeds are reproductive structures that contain what | an embryo and a food supply |
| seeds develope into which generation of plants | sporophyte |
| seeds of these plants are not part of a fruit, male and female reproductive organ are in seperate structures, seeds develop in female structures | cycads, ginkgoes, and joint ferns |
| produces seeds in cones, have needle like or scale like leaves, bear leaves all year round, common in cold or dry habitats | conifers |
| largest and most diverse group of plants, produce flowers and develop seeds that are part of a fruit, divided into two classes called monocotyledons and bicotyledons | flowering plants |
| called "seed leaves", in either two groups called monocots (one seed leaf) or dicots (two seed leaves) | cotyledons |
| female reproductive organ in flowers | pistil |
| at the base of the pistil is the _______ | ovary |
| male reproductive organ in flower | stamen |
| transfer of pollon grains from the anther to the stigma of the pistil | polination |
| __________ provides pollinators with food | nector |
| what is the purpose of fruit | to protect the seeds |
| when does a fruit develope | after fertilization |
