Question | Answer |
What organelle do all organisms in the Plant Kingdom have that allow them to make food? What is the name of the pigment inside of it. | Chloroplast with chlorophyll |
Describe where the seed coat can be found and what job does it perform | Outside - protects the embryo |
Describe where the Cotyledon can be found and what job does it perform | Inside (large mass) - stored food for the embryo |
Describe where the Embryo can be found and what job does it perform | Inside - Baby plant |
What two things does a seed need to germinate? | Water and warmth |
What are three functions of roots? | -Take in water
-Anchor plant
-some store food (i.e. carrot) |
What are the 4 main parts of a plant | -Flower
-Stem
-Leaves
-Roots |
What are three functions of stems? | -Transport materials between roots and leaves
-Holds up leaves/flower
-Some store food (i.e. sugar cane) |
Describe non-vascular | -shorter plants
-no tubes present for transportation of materials
-moss, liverworts, etc |
Describe Vascular | -Taller plants
-Tubes present for transportation of materials
-Trees, flowers, shrubs, etc. |
What are xylem and phloem? | Transport tubes |
Definition of Xylem | Carries water from the roots to the leaves |
Definition of Phloem | Carries glucose (food) from the leaves to the rest of the plant |
What happens to the leaves of celery if the stem is placed in colored water. How do you know this? | The colored water will travel up the xylem and color the leaves of the celery. We know because water is carried upwards by xylem |
What are two functions of leaves? | -Makes food (photosynthesis)
-Captures sunlight |
What are the end products of photosynthesis? | Glucose (food/sugar) and Oxygen |
Name and describe 3 ways a plant can reproduce asexually | -Bulbs - short underground stem that can grow new/identical plants (ie onion)
-Tuber - underground stems that grown new/identical plants from buds (ie potato)
-Sporulation- Identical organism forms from spores released by parent (ie moss)
-Cuttings - A |
Name and describe the 2 ways a plant can reproduce sexually | -Self-pollination - pollen reaches stigma, etc. (between flowers on the same plant
-Cross-pollination - pollen reaches stigma, etc. (flowers on different plants) |
Sexually reproduction provides genetic diversity. Why is genetic diversity good? | Genetic diversity gives us different organisms with a mix of traits. For example, Bubonic plague killed millions, but not everybody. Some people had a mix of traits making them immune to disease so they survived and passed on those traits. |
Definition of Pistil | Center of flower - female part of flower |
Definition of Stigma | top of pistil-captures pollen |
Definition of ovary | bottom of pistil-contains ovules and make seeds |
Definition of stamen | male part of flower |
Definition of anther | top of stamen-releases pollen |
Definition of reproduction | flower function |
When pollen (plant sperm) meets an ovule (plant egg), what does the pollen do to the ovule. This forms the seed | fertilize |
What could plants provide for astronauts in space? | Food, oxygen, boost in spirits, recycled water |
Define hydrotropism | response to water-wilting plants perk up |
Define thigmotropism | response to touch - vines grow along fence |
Define gravitropism | response to gravity - stems grow up, roots down |
Define phototropism | response to light - leaves and stem bend to source |
Define chemotropism | response to chemicals - fertilizer |
