Aerenchyma is a type of parenchyma tissue found in aquatic plants. The large air-filled spaces in parenchyma provide buoyancy to plants and help them float on water.

The correct answer is C.

Collenchyma is a type of simple permanent tissue that is made of elongated and irregularly thickened cells with little intercellular spaces among them. They provide mechanical support and flexibility to plants.

The correct answer is C.

Almond fruit has a hard covering over its seeds because of the presence of sclerenchyma. Sclerenchyma is a simple permanent plant tissue that is made of dead cells. It is long and narrow with thick cell walls made of lignin. It makes plant parts hard and stiff and provides them with strength.

The correct answer is D.

Stomata are small pores present on the epidermis of the leaf. Structurally, two kidney-shaped guard cells are present around the pore. The primary function of stomata is to help in the absorption of carbon dioxide from the atmosphere, which is necessary for carrying out photosynthesis. The oxygen produced during photosynthesis is released into the atmosphere through stomata. Stomata also facilitate the loss of excess water through transpiration.

The correct answer is D.

Phloem is a complex permanent plant tissue. It is made up of sieve tubes, companion cells, phloem fibres, and phloem parenchyma. It helps in the transportation of the food prepared by leaves to various plant parts. It can transport food in upward as well as downward direction.

The correct answer is B.

Stratified squamous epithelium is present in skin. It consists of several layers of squamous epithelial cells, which are arranged in a specific pattern. It protects the skin and prevents its wear and tear.

The correct answer is A.

Ciliated columnar epithelium bears hair-like projections called cilia on its outer surface. Cilia help in pushing mucous which, along with foreign substances, is removed from the air tract.

The correct answer is A.

Blood is a fluid connective tissue. It helps in transporting gases, hormones, nutrients, and wastes materials to various body parts.

The correct answer is A.

Tendons are fibrous connective tissues that possess a great amount of strength. However, their flexibility is limited. They connect muscles to bones.

The correct answer is A.

Adipose tissue helps in the storage of fats in the form of fat globules. It is found below and between internal organs. Fats act as an insulator for trapping body heat, thereby protecting the body from cold.

Hence,the correct answer is option C.

Parenchyma is a simple permanent plant tissue that contains non-specialized cells with thin cell walls. These cells are loosely packed. Parenchyma helps in storing food and providing support to plants. The parenchyma of stem and roots helps in the storage of water and nutrients.

The correct answer is A.
