Question
Answer
Waht are the 3 main parts of vascular plants?   roots, stems and leaves  
🗑
What is the purpose of the root system?   holds the plant in place and stores food  
🗑
The stem and leaves form what system of the plant?   stem and leaves form the shoot system  
🗑
What is the purpose of the shoot system?   is to support the plant,to transport materials and to produce food.  
🗑
What are the 2 types of vascular plants?   seedless and seed  
🗑
How do seedless plants develop?   from spores  
🗑
What is a spore?   a single cel tlhat can develop into a new plant that is exactly like the plant that produced it.  
🗑
What is a seed?   contains an undeveloped plant, stored food and a protective covering.  
🗑
How do seed plants make more of themselves?   when male and female cell are joined.  
🗑
How do seedless plants make more of themselves?   reproduce through spores.  
🗑
What is an angiosperm?   a seed plant that produces flowers.  
🗑
Give 3 examples of an angiosperm.   Fruits, vegetables, and grains  
🗑
What is a gymnosperm?   a seed plant that doesn't produce flowers.  
🗑
Give an example of a gymnosperm.   Evergreen  
🗑

🗑
What is the make part of a flower called?   stamen  
🗑
what does the stamen produce?   pollen grains  
🗑
What is female part of the flower called?   pistil  
🗑
How and why do flowers attract animals?   Flowers have bright colors, scents and nectar to attract animals (insects, birds, small mammals)  
🗑
What is it called when the pollen and egg cell join to form a seed?   Fertilization  
🗑
What is the purpose of fruit?   protects the seeds inside the flower  
🗑
Name 3 ways seeds are dispersed?   animal fur and droppings, through special winged structures seeds might have  
🗑
What is the job of a root in transporting things for the plant?   store food anchor the plant and carry water anf minerals up the stem to the leaves.  
🗑
What is the job of a stem?   develop buds and shoots and usually grows above the ground. It houses the transport system.  
🗑
What is the job of a leaf?   a leaf releases gases into the air and produces sugar.  
🗑
What connects the leaf to the stem or branch?   the petiole connects the leaf to the stem or branch.  
🗑
What do leaves use to produce sugar?   water and carbon dioxide  
🗑
what is the job of the xylem?   to move water and minerals up from the roots.  
🗑
what is the job of the phloem?   to move sugar produced in the plant's leaves to the other parts  
🗑
What is the name of the place where xylem and phloem cells are produced?   cambium  
🗑
what is the function of bark>   protective layer around the tree.  
🗑
what do lighter rings tell you?   formed during spring whe good conditions for growht occur.  
🗑
What do darker rings tell you?   grow during autumn when there is little water.  
🗑
what do larger rings tell you?   there was alot of rainfall that year.  
🗑
Describe a taproot   one large root within a few branching hairy roots  
🗑
3 examples of taproots are   dandelions, beets, carrots  
🗑
where to taproots tend to grow   deep into the soil  
🗑
describe fibrous roots   thing branching roots  
🗑
example of a fibrous root   grass  
🗑
describe prop roots   grow like fingers out of the bottom of a stem  
🗑
example of a prop root   corn  
🗑
describe aerial roots   never touch the ground  
🗑
example of an aerial root   ive and orchids  
🗑
What is photosynthesis?   food making process of plants using energy from sun and water, absorbed by roots and carbon dioxide from the air to make food  
🗑
what is needed for photosynthesis to occur   sun, carbon dioxide (co2) and water (h20)  
🗑
what does carbon dioxide enter the plant?   through the stomata  
🗑
what happens to the stomata when there is little water?   guard cells close and preserve water  
🗑
what happens to the stomata when there is too much water?   guard cells open  
🗑
where does photosynthesis take place   in the choloroplasts  
🗑
what is the name of the chemical that absorbs light energy?   chlorophyl  
🗑
photosynthesis creates sugar for teh plant What is the sugar used for?   for food  
🗑
what is teh waste plants make?   oxygen  
🗑
what is the chemical equation for photosynthesis?   6CO2 + 6H2O + energy > C6H12O6 + 6o2  
🗑
what is the purpose of photosynthesis and Respiration cycle?   provide energy to plants and animals  
🗑
What is the name of the sugar plants produce during photosynthesis?   carbohydrate  
🗑
what is a carbohydrate made from?   carbon, hydrogen, and oxygen  
🗑
Why do animals also depend on photosynthesis?   because of the food chain  
🗑
what do you call it when animals breathe in oxygen?   cellular respiration  
🗑
when would an animal of plant use oxygen?   when the cell needs energy.  
🗑
Why are Photosynthesis and respiration are opposites?   cellular respiration is co2 + h2o, photosynthesis uses co2 and h2o to produce sugars  
🗑
Where does cellular respiration occur in cells?   mitochondria of a cell  
🗑
What is the energy for?   help plant and animal cells grow and repair themselves  
🗑
what do mitochondria use oxygen for?   breaks down stored carbohydrates to release energy.  
🗑
What is the released energy in the mitochondria called?   ATP is the energy released from mitochondria  
🗑
