Quiz On Plants For Grade 5 With Answers

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells, specifically in the chlorophyll pigments. During photosynthesis, plants capture sunlight and use it to produce food, which is essential for their growth and survival. Respiration, on the other hand, is the process by which organisms release energy from food molecules. Foodination, germination, and fertilization are unrelated processes and do not involve the use of light to make food for the plant.

The arrow next to letter E is pointing to the roots. Roots are the part of a plant that typically lies below the surface of the soil and absorbs water and nutrients from the soil. They provide support to the plant and also store food. In the given options, the arrow is pointing towards the bottom part of the plant, which is where the roots are usually located.

Germination refers to the process in which a seed starts to grow and develop into a new plant. During germination, the seed absorbs water and nutrients, causing it to swell and eventually break open. This leads to the emergence of a root, followed by leaves and a stem. Therefore, germination is the correct answer as it accurately describes the initial growth stages of a seed.

Stems are the structural backbone of plants, providing support and transporting water, food, and nutrients between the roots and leaves. However, they do not transport air. The transport of air in plants is primarily facilitated by stomata, tiny pores on the leaves that allow for gas exchange. 

Leaves mostly breathe in carbon dioxide. Leaves have tiny openings called stomata that allow them to take in carbon dioxide from the air. They use this carbon dioxide, along with sunlight and water, to carry out photosynthesis. During photosynthesis, leaves convert carbon dioxide into oxygen and glucose, which is a form of energy that plants use to grow and survive. Therefore, leaves play a crucial role in the exchange of gases, taking in carbon dioxide and releasing oxygen into the atmosphere.

Arrow B is pointing to the seeds.

The main objective of flowers is reproduction. In the reproductive cycle, flowers employ their vibrant petals to entice pollinators like insects and animals. These creatures are drawn to the nectar produced by flowers, which is often found in glands at the base of their petals.

Roots have multiple functions in plants. They absorb water from the soil, allowing plants to stay hydrated. They also absorb nutrients from the soil, which are essential for the plant's growth and development. Additionally, roots anchor the plant in the ground, providing stability and preventing it from being easily uprooted or toppled by wind or other forces. Therefore, the correct answer is "All of the above" since roots perform all of these functions.

The flower is next to letter A because flowers are typically located at the top or uppermost part of a plant. They are responsible for reproduction and contain the plant's reproductive organs, such as the stamen and pistil. Flowers are often brightly colored and fragrant to attract pollinators like bees and butterflies.

When a seed germinates, it begins to grow and develop into a new plant. The first stage of this growth is the emergence of a young plant called a seedling. The seedling is characterized by the presence of a stem, leaves, and roots, which are essential for its survival and further growth. Therefore, the correct answer is seedling.

The process in which a plant takes in carbon dioxide and releases oxygen is called photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose (a type of sugar) and oxygen. This process takes place in the chloroplasts of plant cells, where the green pigment chlorophyll captures sunlight and converts it into chemical energy. 

Germination occurs before pollination, fertilization, and dispersal. Germination is the process by which a seed begins to grow into a new plant. It involves the seed absorbing water and breaking out of its protective seed coat. Once germination occurs, the plant can begin to develop roots, stems, and leaves. Pollination, fertilization, and dispersal happen later in the plant's life cycle. Pollination is the transfer of pollen from the male to the female reproductive organs of a flower, fertilization is the fusion of the male and female gametes, and dispersal is the spreading of seeds to new locations.
