plant parts
| Question | Answer |
|---|---|
| Vascular Bundlees- | -group of tube-like structures in a plant |
| Parts of the Vascular Bundles... | Xylem, Phloem ,Cambium |
| Xylem- | - carries water and minerals from the roots to the top of the plant. |
| Phloem- | -carries sugar and food throughout the plant. |
| Cambium- | -Layer of cells between the xylem and phloem that reproduces to make more xylem and phloem causing the tree to grow wider every year. |
| Cambium produces what every year. | -it produces a new ring every year. |
| Rings tell what? | -They tell the age climate the tree is in, and tree health. |
| Stem provides what? | -It provides support, transportation of food, water, and minerals, some store food, has tuber. |
| Tuber- | -Underground stem that stores food for a plant and can reproduce food. ( example: Potato) |
| 2 types of tubers... | - Herbacious, and woody. |
| Herbacious- | -Soft green stem |
| Woody- | -Stiff, wood stem (cambium cells produce bark) |
| Roots do what? | -They anchor the plant, support the stem,absorbs water and nutrients and transports them,affects size and health of the plant, has primary root. |
| Primary root- | -First root that emerges from seed. |
| 3 types of roots... | Tap root, fiborous roots, arial roots. |
| Tap root- | Thick, long root that grows straight down into the soil (root hairs absorb water and nutrients) |
| Fiborous roots- | -Thin root that grows out in all directions when primary root stops growing. |
| Arial root- | Never touch soil (absorbs moisture from the air) |
| Plants with arila roots are usually called- | They are called parasites. |
| Sepal- | -protects the flower bud until its ready to open. |
| Stamen- | male part of the flower that is a thick stalk with a knob-like structure at the top. |
| Anther- | -knob-like structure at the top of the stamen that produces pollen. |
| Pistal- | -female part of the flower that is located in the center of the flower. |
| Ovary- | -bottom of the flowers pistil that contains 1 or more ovules (where the plant eggs are produced) |
| Style- | -Long, slender stalk that connects the ovary to the top of the pistil. |
| Stigma- | - sticky tip of the pistil that pollen grains stick to |
| Petals | |
| Plants are pollinated by- | -by wind, insects bees and other animals |
| Insect and bees land on stigma and collect ___ on their body. | -They collect pollen. |
| Cross-pollination- | -Transferring of pollen from the anther of one flower to the stigma of another flower. |
| Self-Pollination- | -pollen is transferred from the anther to the stigma of the same flower or to another flower of the same plant. |
| Fertilization- | process of a male cell uniting with the female egg cell to form a ygote. |
| After fertilization, the petals____ ___ and the ____ begins to grow. | Fall off, zygote. |
| Zygot develops into a ___ | Embryo, tiny new plant |
| Ovule become the ___ ___. | Seed coat ( outer covering) |
| Ovary develops int a __- | Fuit. |
| Types of fruit. | 1.Fleshy fruit 2. dry-fruit. |
| Fleshy fruit- | -seeds embedded in their outside flesh (example: strawberry) |
| Dry fruit- | -nuts,corn grains |
| Germination- | -seeds sprout |
| life cycle of a conifer (seeds in cones) | 1.wind blows pollen from male cone to the slightly open scales of a female cone(each cone can only be pollinated by pollen from its own species) 2.scales of female cone close 3.egg is fertilized by pollen in the ovule |
| life cycle of a conifer continued | 4.Ovule develops into the seed and matures 5. Scales open and seed are dispersed by the wind. |
