Answer: The correct answer is- C) vacuole.
Large central Vacuole is a specialized fluid filled organelle, present only in plant cell. It is primarily involved in providing support and shape to the plant cell by maintaining the turgor pressure ( a hydrostatic force that is produced due to the cell contents against the inner side of the cell wall). The central vacuole stores water ( that flows through osmosis) and maintains turgor pressure in a plant cell.
Turgor pressure provides mechanical support and helps in the growth and development of plant.
The plant cell organelle which helps in maintaining the shape of the cell by maintaining turgor pressure is vacuole.
Further Explanation:
The vacuole is an organelle which is mainly present in animal and plant also. There is a difference in size of plant and animal vacuole. Plant cells contain vacuole in the centre of the cell which is much larger than the animal vacuole. Animal cells contain multiple vacuoles that are scattered in the cytoplasm of the cell. They contain membrane-bound sacs. The cell membranes of vacuoles are made up of phospholipids. Proteins are embedded in the cell membrane to transport small molecule. Most plant cells use vacuoles to store water. Animals don’t use vacuole as water storage they store product for endocytosis and exocytosis.
The major functions of vacuoles are:
Manly in plants, a large vacuole is present. This vacuole is enclosed by a cytoplasmic membrane which is tonoplast. This layer can easily stretch and fill with solution. They can easily fill with proton and create acidic environment inside the cell. The development of chemical gradient is helps in transporting material inside and outside of vacuole. They use proton motive force to transport molecule. The vacuole when filled completely with water exerts a pressure on walls of cells called turgor pressure. These force help in maintaining the shape of the cell. Also, allow cells to stand up in rain, wind and hail.

Answer: The correct answer for the fill in the blank is Light dependent phase of photosynthesis.
Photosynthesis ( synthesis of food in presence of sunlight) is primarily divided into Light dependent and light independent phase.
Light dependent phase occurs in the thylakoid membrane within chloroplast and the chemical reactions taking place in this phase are also called Hill reaction. Energy from sunlight is absorbed and converted into chemical energy in the form of ATP and NADPH and Oxygen is produced due to splitting of water in this phase.
The number of growth rings
OB.
The thickness of the growth rings
O c.
The distance between the growth rings
Answer:
The answer to the question is A
Explanation:
The main indicator of a woody plants age like trees are the amount of rings inside, for example if a tree had twenty rings the tree would be twenty years old.
Answer:
The correct answer is ability to reproduce, ability to pass on genetic information, ability to maintain an internal balance and ability to use energy.

B)Glycerol
C)Fat
D)Protein
