Answer:

a. Photosynthesis - Chloroplasts

b. storage of excess pigment and cell sap - Vacuoles

c. gives structural strength and rigidity - cell wall

d. controls all the functions of the cell - nucleus

Explanation:

a. Green plastids called chloroplasts carry out the process of photosynthesis.

  • The thylakoid membranes arranged as grana in chloroplasts contain the pigment chlorophyll, which traps light.
  • The photosynthetic light response takes place in the grana.
  • The dark reaction of photosynthesis takes place in the chloroplast's stroma.
  • Actually, the light reaction is used to create carbohydrates during the dark reaction, which is the synthetic phase of photosynthesis.

b. Sap vacuoles are fluid-filled vesicles that are separated from the cytoplasm by the tonoplast, a membrane that is selectively permeable.

  • Animal cells and immature plant cells both include a number of tiny sap vacuoles.
  • Small vacuoles in mature plant cells combine to produce a single, big central vacuole.
  • Cell sap or vacuolar sap are common names for the fluid found in sap vacuoles.
  • It has organic acids, soluble colors, minerals, carbohydrates, oxygen, and carbon dioxide.
  • Anthocyanins (red, purple, and blue) and anthoxanthins are some of the pigments (ivory to deep yellow).

c. The stiff, rigid outer layer of a plant or fungus cell is called the cell wall.

  • It safeguards and supports the structural integrity of the cells.
  • Cellulose, a polymer of glucose, is a carbohydrate and the most durable part of the cell wall.
  • A secondary cell wall is created when the primary cell wall is supplemented with lignin.
  • The strength and rigidity of the cell are increased by the secondary cell wall.
  • It is primarily found in the tissues of living plants.

d. The most crucial component of the cell, the nucleus, governs all cellular functions by regulating the enzymes needed for cellular processes.
