What is its primary function of the structure of a plant cell?

Answers

Answer:Chloroplasts are organelles that are crucial for plant cell function. These are the structures that carry out photosynthesis, using the energy from the sun to produce glucose. In doing so, the cells use carbon dioxide, and they release oxygen.

Explanation:hope this helps

In all organisms, the cell is the fundamental unit of life. Plants, like animals and humans, are made up of multiple cells. The cell wall of the plant cell gives the cell its shape and covers the cell. Other organelles, in addition to the cell wall, are associated with various cellular activities.

What organelles are present in cell ?

Plant cells are eukaryotic cells that differ from other eukaryotic organisms in several fundamental ways. There is a nucleus and similar organelles in animal and plant cells. The absence of a cell wall outside of the cell membrane is one of the plant cell's distinguishing characteristics.The building blocks of plants are called plant cells. The primary function that plant cells perform is photosynthesis.The chloroplasts of a plant cell are where photosynthesis takes place. It is the way that plants use sunlight, carbon dioxide, and water to prepare food. During the process, ATP is produced as energy.Water and nutrients are transported from the roots and leaves to various parts of the plant by a few plant cells.A mature, higher plant's cells become specialized to carry out particular vital functions that are necessary for their survival. Some plant cells are responsible for storing food, while others transport water and nutrients.Parenchyma cells, sclerenchyma cells, collenchyma cells, xylem cells, and phloem cells are the specialized plant cells.

Plants do photosynthesis to make the glucose and cellular respiration to break the glucose down for energy.
True
False

Answers

Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration. ... For plants to perform photosynthesis they require light energy from the sun, water and carbon dioxide. Water is absorbed from the soil into the cells of roots. And during the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
