What are the reproductive parts of plants and their functions Grade 5?
As a plant’s reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 1). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament. The anther is a key part of the reproductive process of a flower. This is because it produces and houses pollen grains. Pollen grains are the male sex cells for the flower. Similar to humans having male and female gametophytes, flowers have pollen and ovules.Flowers are the reproductive part of a plant. It is also an excellent source of food for many living organisms, such as honeybees, as they are a rich source of nectar.
What are the parts of a plant grade 4?
The four basic parts of plants are roots, stems, leaves and flowers. Roots absorb water and minerals for the plant and hold it in the ground. Stems transport water and food throughout the plant and provide support. Plants are living things and have a basic structure with different parts. Can you see some of the different parts in this picture? Plants have different parts like leaves, flowers, seeds, stems, fruit and roots.Plants have basic needs. Plants need sunlight, water, air, and nutrients from soil. Plants can survive and grow only when all their needs are met.
What are the main parts of the plant that undergo photosynthesis grade 5?
The leaves of a plant have the important function of carrying out photosynthesis (foh tuh. SIN thuhâš«sis), or the process of making food. Cells within the leaf’s epidermis make up the plant’s main food factory. To perform photosynthesis, leaves need three raw materials: sunlight, water, and carbon dioxide from air. This study demonstrates the essential roles of roots, stems, and leaves in plant function and growth. Roots are responsible for nutrient and water uptake, stems provide structural support and transport, and leaves facilitate photosynthesis and transpiration.The roots of a plant take up water and nutrients from the soil. The roots also keep the plant steady and upright in the soil. The stem carries water and nutrients to different parts of the plant. The leaves use light from the sun, along with carbon dioxide from the air and water to make food for the plant.Overall, the glucose created in photosynthesis helps plants respire, make fruit, build cells, create amino acids which are then made into proteins, store energy as starch, and create seeds. These processes are all necessary for life.Leaves are vital to the survival of plants. They help plants in a variety of ways, including producing food and oxygen through photosynthesis, balancing water loss, regulating gas exchange, and transporting the products of photosynthesis.The amount of light, the carbon dioxide supply, temperature, water supply, and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants.
