Plants Pt. 1
Which vegetable has only leaves: carrots, broccoli, celery, or lettuce?
Lettuce
Maria was doing an investigation that contained the following: remove the stamen. Lightly wipe the tip of the stamen against the black paper. Some of the powdery pollen should stick to the paper. What was Maria studying?
Sexual reproduction in plants.
What adaptation does the deer have for escaping from the mountain lion?
Lakes are home to many kinds of birds. Which feet are most likely the adaptation of a bird that swims in water to find food?
Duck feet
The root emerges first because it is the structure that takes in water and nutrients from the soil. A plant cannot grow without water.
Which part of a vascular plant anchors the plant in the ground?
Root
Virginia Creeper Vine
Feature Description
flower small, green-yelow
growth pattern tall, twining
leaf compound, five parts
stem woody, smooth
The life cycle of a Virginia Creeper Vine includes sexual reproduction. Which feature of the plant is used for sexual reproduction?
Stem, leaf, growth pattern, or flower?
Flower
Hatching
A safflower is a plant with small seed that has a thick shell. Birds need to crack open the shell to eat the seed. Which type of beak would be best suited to eating safflower seeds?
Short and Strong
The first plants that lived on land were nonvascular plants similar to today's mosses. Today there are more vascular plants than nonvascular plants. Explain why vascular plants might be more successful than nonvascular plants.
Nonvascular plants do not have true roots, so they probably transport water less efficiently than vascular plants. Since they soak up water and minerals like a sponge, they might die if the environment becomes too dry. Vascular plants have a more efficient way of transporting water and minerals throughout the plant, contrasting any of the factors above. (does not have to be this long but include the difference between vascular and nonvascular plants).
Len has two green plants. He keeps one on a sunny windowsill. He keeps the other one in a shady part of the same room. He gives both plants the same amount of water. What will happen to the two plants?
The plant in the sun will grow faster.
Which adaptation keeps the plant below from losing water?
Flat, waxy leaves
A female manatee usually has only one pup at a time. Which word best describes this part of the life cycle?
-death
-growth
-maturity
-reproduction
Reproduction
Long and thin
Seeds may remain dormant, or inactive for days, weeks, or months after they reach the ground. This means that they do not start to germinate immediately. What is one reason that seeds may remain dormant?
Seeds may stay dormant if the weather is not suitable for germination. It might be too cold or the soil might be too dry. (include unfavorable environmental conditions, drought, freezing temperatures).
Gail puts a green plant in a closed wooden box. She gives it good soil and plenty of water. What will happen to the plant?
It will die because it does not get any sunlight.
The magnolia tree is a flowering plant. The pine tree is a nonflowering plant. Both trees have similar life cycles. What is the order of events in the life cycles of both plants?
Pollination, fertilization, seed, seed dispersal
The southern pine beetle damages pine trees all over the southern U.S. The female beetle finds a tree, digs holes, in the wood, and lays her eggs deep inside the tree. An egg hatches and the larva eats wood inside the tree. Then it crawls to the wood just under the bark, where it becomes a pupa. Once the pupa turns into a beetle, it crawls out of the tree and flies away. How many stages of the southern pine beetle's life cycle are spent entirely in a tree?
3 life cycles
A stilt is a bird found in wetlands. It wades in the shallow water and has a slender, sharp beak. What does the stilt most likely eat?
Desert Arctic
Thin fur Thick fur
Large ears Small ears
Long legs Short legs
Small size Large Size
Which of the following is the best explanation of why different plants leaves have different textures?
-to help them produce sugars
-to help them take in water
-to help them hold water
-to help them adapt to the environment
To help them adapt to the environment
Which adaptation does a rattle snake have living in the desert.
