True or False? The response of a plant to a stimulus is called tropism

True
False

Correct Answer

A. True

Explanation

The response of a plant to a stimulus is indeed called tropism. Tropism refers to the directional growth or movement of a plant in response to an external stimulus, such as light, gravity, or touch. These responses help plants adapt to their environment and optimize their growth and survival. Therefore, the statement "The response of a plant to a stimulus is called tropism" is correct.

This is a trait that helps a plant survive in its environment

Stimulus
Light
adaptation

Correct Answer

A. adaptation

Explanation

Adaptation is a trait that helps a plant survive in its environment. It refers to the process by which plants adjust to their surroundings in order to increase their chances of survival and reproduction. This can include physical changes in the plant's structure, such as the development of thorns or the ability to store water, as well as behavioral changes, such as the timing of flowering or the direction of growth towards a light source. By adapting to their environment, plants are able to better compete for resources, avoid predators, and withstand harsh conditions.

Plants respond to their ___________________ in many ways.

Parts
Nutrients
Environments
None of the above

Correct Answer

A. Environments

Explanation

Plants respond to their environments in many ways. They can adjust their growth, development, and physiological processes according to various environmental factors such as temperature, light, water availability, and soil conditions. These responses enable plants to survive and thrive in different habitats and adapt to changes in their surroundings. Therefore, the correct answer is "environments."

A layer of tough cells that protect the growing tip of the root is called the _________________________.

Skin
Shield
Cortex
Root cap

Correct Answer

A. Root cap

Explanation

The correct answer is root cap. The root cap is a layer of tough cells that protects the growing tip of the root. It acts as a shield, providing protection to the delicate cells behind it. The root cap also plays a role in sensing gravity and guiding the root as it grows downward. The other options, skin, shield, and cortex, do not accurately describe this specific layer of cells found in the root.

What happens when a plant reacts to a stimulus?

it changes its direction of growth
It grows stronger
It grows weaker
It stops growing

Correct Answer

A. it changes its direction of growth

Explanation

Plants have the ability to respond to various stimuli in their environment, such as light, gravity, touch, or chemicals. When a plant reacts to a stimulus, it changes its direction of growth. This is known as tropism, where the plant grows towards or away from the stimulus. For example, phototropism is when a plant bends towards a light source, while gravitropism is when a plant grows in the direction of gravity. This adaptive response allows plants to optimize their growth and survival in their surroundings.

This is something in the environment that causes a living thing to respond

Animal
Stimulus
Adaptation
None of the above

Correct Answer

A. Stimulus

Explanation

A stimulus is something in the environment that causes a living thing to respond. It can be a physical or chemical factor that triggers a reaction or behavior in an organism. Stimuli can include things like light, temperature, sound, touch, or even the presence of other organisms. When a living thing detects a stimulus, it can initiate a response or change in its behavior or physiology. This response allows the organism to adapt and interact with its environment effectively.

Roots help plants survive in three main ways. Which way below is NOT one of these main ways?

Roots hold or anchor the plant in the soil.
Roots draw up water and minerals from the soil.
Roots draw up food for the plant.
Some roots store food for the plant

Correct Answer

A. Roots draw up food for the plant.

Explanation

Roots help plants survive by holding or anchoring the plant in the soil, drawing up water and minerals from the soil, and storing food for the plant. However, roots do not draw up food for the plant. Food production occurs in the leaves through the process of photosynthesis, where plants convert sunlight into energy. Therefore, the correct answer is that roots do not draw up food for the plant.

A large thick root with a few hairy branching roots is (an)_________________.

Fibrous root
Taproot
Phloem
Simple

Correct Answer

A. Taproot

Explanation

A taproot is a large thick root with a few hairy branching roots. It is the main root of a plant that grows vertically downwards and gives rise to lateral roots. This type of root system is commonly found in dicot plants and provides stability and anchorage to the plant. The taproot also helps in absorbing water and nutrients from the soil. In contrast, a fibrous root system consists of many thin and moderately branching roots that arise from the base of the stem. Phloem is a type of plant tissue responsible for transporting sugars and other organic compounds. "Simple" does not relate to the given description of a large thick root with branching roots.

What causes plant roots to grow downward?

Nutrients in the soil
Weeds
gravity
Other plants in the area

Correct Answer

A. gravity

Explanation

Plant roots grow downward due to gravity. Gravity is a force that pulls objects towards the center of the Earth. The roots of plants are sensitive to gravity and will naturally grow in the direction that allows them to reach deeper into the soil. This downward growth is important for plants to anchor themselves in the ground and absorb water and nutrients from the soil.

Water and minerals pass through the root's ____ and move upward in the _ to all the parts of the plant, while food flows downward in the _____________. Choose the words below that appear in the correct order to fit into the blanks to make this statement true and accurate.

Xylem, cortex, phloem,
Phloem, xylem, cortex
Cambium, cortex, phloem
Cortex, xylem, phloem

Correct Answer

A. Cortex, xylem, phloem

Explanation

Water and minerals pass through the root's cortex and move upward in the xylem to all the parts of the plant, while food flows downward in the phloem.
