plants-stems-roots-leaves
| Question | Answer |
|---|---|
| What do Roots do? | Anchor the plant to the ground, absorb water and minerals, and sometimes store food. |
| Define Fibrous | a dense, tangled mass of many roots. |
| Define Taproot | main root with branches of roots. |
| What does a Root cap do? | Protect the cell |
| Define Root Hairs | absorb nutrients and water |
| What does the root hairs collect? | xylem (water) and phloem (food) |
| What do stems do? | transport water and nutrients between the roots and leaves, and support the leaves. |
| what are the two different types of stems? | Woody and herbaceous |
| Define Woody | solid stem |
| define herbaceous | Soft stem such as a asparagus |
| What do stems consist of? | Heartwood (old xylem that support the tree), xylem tissue (transport water), phloem tissue (transport food), cambium ( tissue that produces xylem and phloem), cork (protects the cell), and bark (protects the inner cells). |
| What do leaves do? | Leaves capture the sun's energy and carry out photosynthesis. |
| Define guard cells (surface cell) | top and bottom the protect the leaf. |
| Define Mesophyll | the inner tissue (prenchyma) of a leaf, containing many chloroplasts. |
| What are the veins that pass through the leaves? | xylem and phloem |
| Define stomata | small openings or pores that open and close to allow these things to pass: water vapor, carbon dioxide, and oxygen |
| The equation of photosynthesis | carbon dioxide + water + sun energy --> O2 + Glucose (sugar) |
| Define transpiration | the process by which water evaporates from plant's leaves. |
| Define cuticle | waxy substance that also regulates water loss. |
| define embryo | an organism that develops from the zygote |
| define zygote | the fertilized egg |
| define endosperm | food for the embryo inside the seed |
| define cotyledon | part of the embryo. Often into the first leaves |
| define seed coat | the outer covering of the seed, protects the embryo |
| define germination | when a seed starts to grow into a plant |
| what 3 things does a plant need in order to germination? | moisture, oxygen, and the proper temperature |
| why do plants disperse seeds? | to increase their population and to prevent competing with the parent for resources |
| how do plants disperse? | wind, fruit, burrs, ejection, water, and ANIMALS |
| What does the embryo provide for the roots, stems, and leaves? | The material |
| What does the embryo feed on until it can make its own food? | The endospore |
| define flower | the reproductive structure of an angiosperm. |
| define pollintaion | the transfer of pollen from male reproductive structure to female reproductive structures. |
| define sepals | protect the developing flower and are often green |
| define petals | generally the most colorful part of the flower. petal's shapes depend on the flower. |
| define staments | the male reproductive parts |
| define pistils | the female reproductive parts, usually in the center of the flower. |
| define ovary | protects the seeds as they develop |
| define sporophyte | the stage where the plant produces spores |
| define gametophyte | the stage where the plant produces two kinds of sex cells: the sperm cell and the egg cell |
| define annuals | flowering plants that complete a life cycle within one growing season |
| define biennials | angiosperms that complete their life cycle in two years |
| define perennials | flowering plants that live for more than two years |
| define perfect flowers | have both a stamen and a pistil |
| define imperfect flowers | either have a stamen or a pistil |
| define composite flowers | many perfect flowers; daisy |
| What are the 6 steps | 1. seed 2. germination 3. stems & roots 4. leaves 5. flowers 6.pollination |
| define cross-pollination | occurs when pollen is carried from one plant to another of the same species. variation is the result |
| define hybrid | plants are cross-pollinated to achieve specific features. Pluots, tangelo. |
| What are the nine parts of the flower | sepal, petal, ovary, style, pistil, stigma, stamen, filament, and anther |
| What are the basic parts of a plant? | Roots, stems, leaves, flowers, fruit, seeds |
| What are the stages of a plant's life cycle? | seed, germination, roots and stems, leaves, flower, pollination |
| What are the two types of leaves? | simple and compound. |
| In the food making process what things are changed into glucose? | CO2, water, chlorophyll, light energy |
| define fertilization | the joining of pollen with an ovule to form a seed. |
| What are the 7 things needed to grow? | room to grow, temp, light, water, air, nutrients, and time. |
| How do nonflowering plants reproduce? | spores which disperse. |
