How Much Do You Know About Plants Survival?

Photosynthesis is the correct answer because it is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. During photosynthesis, plants use the energy from sunlight to produce food, which is essential for their growth and survival. Respiration is the process by which plants and animals convert glucose and oxygen into energy, while transpiration is the process by which plants release water vapor through their leaves. None of the above options accurately describe the food-making process in plants except for photosynthesis.

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.

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 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."

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.

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.

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 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 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.

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 cortex and move upward in the xylem to all the parts of the plant, while food flows downward in the phloem.
