| Question | Answer |
|---|---|
| What does the anther do ? | Male part , produces and contains pollen |
| What does the stamen do ? | Male part, contains the anther and filament |
| What does the ovary do ? | Female part, contains the ovule and fertilizes it here |
| What does the petal do ? | Provides visable single, attracts pollinators |
| What does the style do ? | Female part, holds up Stigma |
| What does the sepals do ? | protect the flower as a bud |
| what does the filament do ? | Male part , holds up the anther |
| What does the pistill ? | Female part, contains the style and stigma |
| What does the stigma do? | Female part ,collects the pollen |
| What is the function of the stem ? | Holds the plant upright ,brings plant closer to the sun |
| What is the function of the roots ? | Collects Nutrients and water for the plant |
| What is the function of the leaf ? | Collects light and turn into sugar for photosyntheies |
| What is the function of the flower ? | Are used to make fruits and reproduce |
| What is the function of the root cap ? | Protects the root from injurys |
| What is the function of the root hairs ? | To increase surface area and collect more nutrients |
| What is the function of the meristematic tissue ? | to conduct mitosis |
| What is the function of the vasscular tissue ? | contains the xylem and pholem |
| What is the function of the phloem ? | transfer of sugars through out the plant |
| What is the function of ground tissue ? | produces carbohydrates and stores them |
| What is the function of the dermal tissue ? | protect the plant |
| What is the function of the xylem ? | transports water and nutrients from roots to plant |
| Xylem is ? | made of dead cells, thick cell wall, impearable, no cytoplasma, carried in leaves,moves upward, and made of tissue fiber |
| Pholem is ? | Mde of living cells, thin cell wall, permeable, has cytoplasma, stored in gorwth parts, moves up and down, made of companion cells |
| What is the function of the fruit? | protects of the seed |
| What is the function of cones ? | produces pollen carried by wind to fertilize females |
| What is the function of the seed ? | Protects embryo |
| Function of gaurd cells ? | help regulate the rate of transpiration |
| what is the function of the stoma ? | controls exchange of gasses |
| what is the function of the cambium tissue / | produces new pholema on outside new xylem on the inside |
| Describe a fibrous root ? | has small fiber like roots |
| Describe cauline roots ? | roots tht come straight out from stem |
| decribe tubercular roots ? | tail like root |
| Describe taproot ? | grows out like a tree |
| what id needed to make ATP ? | ADP+ peptide bound + energy |
| What is needed to make ADP ? | Removel of peptide bound - energy |
| What does ATP do ? | STORES ENERGY |
| Describe photosynthesis ? | Collects light water and carbon in the thylakoid and produces sugar and oxygen |
| Describe cellular respiration ? | In the matrix collects sugar glycolysis and makes carbon, in the inner mebrane collects oxygen and produces water |
| In cellular respiration causes what ? | Fermentation tht produces latic acid or acholic |
| How does the transportaion work ? | either through transipiration- evaporation of water fromparts exposed to air or choesion/adhesion - creats tension Absorbtion - pulled into roots |
| What are the two types of Meristematic tissue ? | primary-lengthens roots stems sceondary - widens roots andd stems |
| What is the cell cycle ? | Gap 1, Synthesis , Gap 2, Mitosis, Cytokinesis |
| What happens in gap 1, synthesis, and gap 2 ? | Gap 1 - Cells grow carry out normal function Syntheisis - DNA synthesis Gap 2- countinus growing |
| What is the first stage in mitosis ? | Prophase -Nuclear membrane breaks chromosomes begin to move to poles |
| What is the 2nd stage in Mitosis ? | Metaphase - spindle fibers attach to each one and meet at the equator |
| What is the 3rd phase in mitosis ? | Anaphase - Chromatids seprate to each side of the cell |
| What is the 4th phase in mitosis ? | Telephase - Nuclear membrane form ,still together |
| What happens in cytokinese ? | Divides cytoplasma into two new cells |
| What are the two tumors cancer cells form ? | Benign- remain in one spot can be removed Maignant- spreads around |
| Mitosis foes through ? | asexual reproduction and binarry fission |
| Bacteria goes through ? | Binnary fission |
| What is a diploid and where are they found ? | Has 46 chromosomes found in mitosis cells |
| What is heploid and where is found ? | Has 23 chromosomes found in miosis cells |
| What are gametes ? | sex cells |
| What are somatic cells ? | Anything but a sex cell |
| What is a zygote / | happens through fertilization a fertilized egg |
| How many fases are their in meosis ? | prophase 1 -telophase 2 |
| What is another word for fermenaion ? | Anerobic respiration |
| when bacteria needs oxygen it is ? | aerobic bacteria |
| when bacteria dosent need oxygen it is ? | anaerobic bacteria |
