Question Discussion & Solution

The correct answer is Transpiration.

• Transpiration is the loss of water from a plant in the form of water vapour.

 Additional Information

• The amount of water that plants transpire varies greatly geographically and over time.
• The transpiration depends upon
  • Temperature,
  • Relative humidity,
  • Wind and air movement,
  • Soil moisture availability and
  • Type of plant.

Guttation

• Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of some vascular plants.

Evaporation

• Evaporation is the process by which water changes from a liquid to a gas or vapour.

Translocation

• The movement of sucrose and other substances like amino acids around a plant is called translocation.

Concept-

• A cell is defined as the smallest unit of an organism with a nucleus.
• cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids.

Key PointsParts of cell-

Cell membrane

• It is also called the plasma membrane,
• It is found in all cells and separates the interior of the cell from the outside environment.
• It is the outermost wall in the animal cell and placed next to the cell wall in the plant cell.
• Being an outer boundary of a cell, it provides shape to the cell.

Cell wall

• A cell wall is defined as the non-living component, covering the outmost layer of a cell.
• cell wall separates the interior contents of the cell from the exterior environment.
• It also provides shape, support, and protection to the cell and its organelles.

Nucleus

• A nucleus is defined as a double-membraned eukaryotic cell organelle that contains genetic material.
• It contains the cell’s hereditary information and controls the cell’s growth and reproduction
• It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth, and a host of other important functions.

Ribosomes

• The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.

Additional Information  Cell was discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today's scientific advancements.
