Structure and Function
What is the function of the phloem?
What is: transports sugars and amino acids from the leaves down to the rest of the plant.
Producers use energy from the sun to create ________; or usable chemical energy.
What is: Glucose
The fertilized ovule of a flowering plant that contains an embryo and a protective covering is called a ___________?
What is: Seed
What system is in charge of absorbing water and minerals, anchoring the plant into the soil, and storing food?
What is: Root System
Multicellular organisms work consistently to maintain a stable internal environment. This environment is called?
What is : Homeostasis
A seed is anchored into the ground by its?
What is: Roots
In plants, this process uses carbon dioxide, water and light energy in the leaves to produce glucose and oxygen.
What is : Photosynthesis
What are at least 2 ways that seeds are dispersed?
What is: Wind, water, animal, gravity, explosive power.
What is the name of the fluid that moves through a plant’s vascular tissue carrying water, minerals, and sugars to all parts of the plant?
What is: Sap
The responses of plants to external stimuli are called:
What is: Tropisms
What is the function of the xylem?
What is : To transport water and minerals from the roots to the rest of the plant.
What is the process in which a new plant begins to grow and sprout from a seed?
What is: Germination
This plant structure contains the egg cell and after fertilization it develops into a seed.
This plant system includes the stems, leaves, and flowers and is mainly responsible for photosynthesis and support above the ground.
What is : Shoot system
A plant is placed on its side near a window. After several days, the roots grow downward (positive) while the stem grows upward (negative). What type of tropism is being demonstrated?
What is : Gravi or Geotropism
What two types of tissues make up a plants vascular tissue and what does each transport?
What is : Xylem/water and phloem/ sugars
What structures on the leaves allow carbon dioxide to enter during photosynthesis and water vapor to exit during transpiration?
What are: Stomata
These two flower structures work together in sexual reproduction; one produces pollen and the other contains the ovule.
What are: Stamen and Carpel
If some of the xylem of a young oak tree were destroyed, it would most likely interfere with the tree's ability to:
What is : Pull water to leaves.
What is: Hormones
If the phloem is damaged, what happens to the transport of sugars in plants and how might this affect the roots?
What is: Sugars made in the leaves can't be transported to other parts of the plant. The roots will not receive the nutrients they need, which can harm or kill the plant.
The waxy cuticle on the leaves of a tree is an adaptation that serves primarily to protect against?
What is: Water loss
What process is occuring through the following steps :
1. Pollen from the anther sticks to a stigma and travels down the style to an ovary.
2. A sperm cell in pollen fertilizes the egg, creating a seed.
3. Ovary of the flower ripens into a fruit containing seeds.
What is : Sexual reproduction
What term describes the pressure created when water inside a plant cell’s central vacuole pushes outward against the cell wall, helping maintain cell rigidity and plant support?
What is : Turgor Pressure
Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as?
What is: Phototropism
