How do plants demonstrate the seven life processes?

Plants demonstrate the seven life processes through photosynthesis, growth, reproduction, sensitivity, excretion, nutrition, and movement.

Plants carry out photosynthesis, which is a process that converts light energy, usually from the sun, into chemical energy that can be later released to fuel the plant's activities. This is the plant's way of nutrition. They absorb water and minerals from the soil, carbon dioxide from the air, and energy from the sun to produce glucose and oxygen. This process is vital for the survival of the plant and also contributes to the oxygen supply on Earth.

Growth in plants is a continuous process, unlike in animals. They grow throughout their lifetime, adding new cells to their body through cell division. This growth is not only in size but also in complexity, as they develop different parts like roots, stems, leaves, and flowers.

Reproduction in plants can occur in two ways: sexually and asexually. Sexual reproduction involves the fusion of male and female gametes, resulting in seeds that grow into new plants. Asexual reproduction, on the other hand, involves the growth of a new plant from a fragment of the parent plant.

Sensitivity in plants is demonstrated by their response to stimuli. For example, plants can respond to light (phototropism), gravity (gravitropism), and touch (thigmotropism). These responses help them to maximise their exposure to sunlight and thus, their ability to photosynthesise.

Excretion in plants involves the removal of waste products. Unlike animals, plants do not have a specific organ for excretion. Instead, they get rid of waste products through different parts. For instance, oxygen is a by-product of photosynthesis and is released through the stomata in the leaves.

Lastly, plants demonstrate movement, although not in the same way as animals. They do not move from place to place, but they do show movement in response to stimuli. For example, the opening and closing of flowers, the movement of leaves towards light, and the growth of roots towards water.
