The roots of a plant are responsible for taking in water from the soil. They have specialized structures called root hairs that increase the surface area for absorption. These root hairs absorb water and minerals from the soil through a process called osmosis. The water is then transported through the stem to other parts of the plant, such as the leaves, where it is used for various functions like photosynthesis. Therefore, the correct answer is roots.

Chlorophyll is a pigment found in plants that is responsible for absorbing light energy from the sun during photosynthesis. It specifically absorbs red and blue light, while reflecting green light, which is why plants appear green to our eyes. Therefore, the correct answer is green.

Photosynthesis is the process by which plants and some other organisms convert sunlight into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells, where chlorophyll absorbs sunlight and uses it to combine carbon dioxide and water to produce glucose and oxygen. This energy-rich glucose is then used by the plant for growth, reproduction, and other metabolic activities. Therefore, the correct answer is "the process of using sunlight to make energy."

Leaves are the part of a plant that makes the most food through a process called photosynthesis. They contain chlorophyll, which captures sunlight and converts it into energy. This energy is used to combine carbon dioxide and water to produce glucose, the primary source of food for the plant. Leaves have a large surface area, allowing them to absorb more sunlight and carry out photosynthesis efficiently. Additionally, leaves have tiny openings called stomata that allow for the exchange of gases, further aiding in the process of photosynthesis.

Plants growing towards the sun, water, or good soil is known as a tropism. Tropism is a biological phenomenon where plants respond to external stimuli by growing or bending in a particular direction. In this case, the plants exhibit positive tropism as they grow towards the sun, water, or good soil. This behavior allows the plants to maximize their exposure to sunlight for photosynthesis, access water for hydration, and obtain nutrients from fertile soil. Therefore, the statement is true.

Trees that have broad leaves are called deciduous. This is because deciduous trees shed their leaves annually, typically in the autumn. This characteristic distinguishes them from conifers, which have needle-like or scale-like leaves that are usually evergreen. Deciduous trees include popular species such as oak, maple, and birch, and they are known for their vibrant foliage in the fall.

Oak Tree produce blossom flowers in the spring

Heartwood is the correct answer because it refers to the type of wood inside a tree that is stiffer and helps hold the tree up. It is the older, non-living part of the tree trunk that provides structural support and strength. Unlike sapwood, which is the younger, living part of the wood responsible for transporting water and nutrients, heartwood is denser and more durable. The cambium is a layer of actively dividing cells responsible for the growth of new wood and bark, while the inner bark is a layer that transports nutrients throughout the tree.

Sapwood is the correct answer because it is the part of a tree that is responsible for moving water up the stem. Sapwood is the outermost layer of the wood and contains living cells that transport water and nutrients from the roots to the rest of the tree. It is lighter in color compared to heartwood and plays a crucial role in the tree's growth and survival.

Plants undergo a process called photosynthesis, where they convert carbon dioxide into oxygen. Therefore, plants do not breathe out oxygen, but rather release it as a byproduct. On the other hand, they take in carbon dioxide from the atmosphere and use it to produce glucose and oxygen through photosynthesis. Hence, the correct answer is carbon dioxide.
