the final exam for st georges episcopal 6th science
| Question | Answer |
|---|---|
| two characteristics of plants | autotrophic eukaryotes |
| photosynthesisthe process by which plants make their own food | photosynthesis |
| the boundary that surrounds a plant cell | cell wall |
| a chemical that makes the cell wall rigid | cellulose |
| the structures in which food is made,photosynthesis | Chloroplasts |
| a sac like storage area where food and water is stored | vacuole |
| groups of similar cells that preform a specific function in an organism | tissues |
| found in the chloroplasts, gives it the green color | chlorophyll |
| for plants to survive on land they must have/ be able to | obtain water and other materials from their surroundings retain water transport materials throughout the plant support their bodies reproduce successfully |
| a waxy waterproof layer that covers the leaves of most plants | cuticle |
| an internal system of tube like structures through which water and food move inside the plant | vascular system |
| _____ occurs when a sperm cell unites with an egg cell | fertilization |
| the fertilized egg | zygote |
| the first stage of a plant when it is able to produce spores, the tiny cells that can grow into new organisms | sporophyte |
| a spore develops into the plant's other stage, called _____ the plant produces two kinds of sex cells in this stage | gametophyte |
| the two kinds of sex cells, perm cells and egg cells | gametes |
| the life cycle of the plant | egg - sporophyte - gameophyte |
| reaction equation of photosythesis | water + carbon dioxide + sunlight = air and glucose (sugar) |
| nonvascular plants | low-growing plants that lack vascular tissue ex: moss, hornworts, liverworts |
| thin root-like structures called _______ anchor the moss and absorb the water and nutrients from the soil | rhizoids |
| Sphagnum moss grows in a type of wetland called a ______ | bog |
| Over time,the mosses become compressed into layers and form a blackish- brown material called ______ | peat |
| liverworts, hornworts, and mosses | lowgrowing, non-vascular, |
| two characteristics of ferns and their relatives | vascular tissue use spores to reproduce |
| unlike mosses, ferns are | vascular plants, plants that have vascular tissue |
| a ferns leaf | frond |
| fern gametophytes | tiny plants that grow low to the ground |
| all seed plants share two characteristics | the have vascular tissue and use seeds to reproduce |
| most seed plants live_____ | on land |
| the vascular tissue through which food moves | Phloem |
| water and nutrients travel in the vascular tissue called _______ | xylem |
| structures that contain a young plant inside a protective covering | seeds |
| the three important parts of a seed | embryo, stored food, and a seed coat |
| the young plant that develops from the zygote | embryo |
| in some plants, food is stored inside on or two seed leaves, or _______ | cotyledons |
| a seed must have three things to develop into a new plant | water light nutrients |
| the scattering of seeds | seed dispersal |
| the early growth stage of an embryo | germination |
| the most numerous parts on many plants | the leaves |
| the function of leaves | leaves capture the sun's energy and carry out the food-making process of photosyntesis |
| the underside of the leaf has small openings, or pores called _____ | stomata they look like tiny mouths |
| how the stomata works | carbon dioxide enters the leaf through the stomata sugar and and oxygen are produced form the carbon dioxide and water |
| the process by which water evaporates from a plant's leaves | transpiration they slow down transpiration by closing the stomata |
| the stem | the stem carries substances between the plant's roots and leaves. The stem also provides support for the plant and holds up the leaves so they are exposed to the sun |
| a layer of cells inside the phloem | the cambium |
| the roots | the roots anchor the plant in the ground and absorb water and nutrients from the soil |
| contains dead cells, protects the root from injury from rocks and other material as the root grows through the soil | root cap |
| a seed plant that produces naked seeds | gymnosperm |
| characteristics of gymnosperms | every gymnosperm produces naked seeds.In addition, many gymnosperms also have needlelike or scalelike leaves, and deep- growing root systems |
| the four groups of gymnosperms | cyads, ginkgos, gneophytes, conifers |
| cyads | live only in tropical areas |
| ginkgo | only one species of ginkgo exists today |
| gnetophytes | live in hot dry deserts in south africa, least likely to be seen |
| conifers | a cone bearing plant, christmas trees, most likely to see, the largest group of gymnosperms, |
| reproductive structures | cones |
| the gymnosperms produce two types of cones | male cones and female cones |
| _____ contains the microscopic cells that will later become sperm cells | pollen (located in the male cone) |
| a structure that contains an egg cell | ovule (located i the female cone) |
| the transfer of pollen from a male reproductive structure to a female reproductive structure | pollenation |
| a plant that produces seeds that are enclosed in a fruit | angiosperms |
| the protective "vessle" where the seeds develop | ovary |
| the ovary is located within an angiosperm's ______ | flower |
| Characteristics of angiosperms | fruit flowers |
| colorful structures that you see when flowers open | petals |
| leaflike structures that enclose a flower when it is still a bud | sepals |
| the male reproductive part | stamen |
| female reproductive part | pistil |
| how angiosperms reproduce | pollen falls on stigma sperm cell and egg cell join together in the flower's ovule zygote develops into the embryo part of the seed |
| angiosperms with only one seed leaf | monocots corn wheat rice lilles and tulips flowers have a multiple of three leaves |
| angiosperms with two seed leaves | dicots roses violets dandelions oak maple beans and apples either four or five petals or a multiple of the two |
| a plant's growth response toward or away from a stimulus | tropism |
| a chemical that affects how the plant grows and develops | hormones |
| one important hormone that speeds up the rate at which a plants cells grow | auxin |
