Define the following: a) Dermal tissue.
b) Organ system.
c) Collenchyma.
d) Anaerobic respiration.
e) Cell.
Answers
Explanation:
1 the dermal tissue is the outer protective layer of the primary plant body like leaves root flowers fruits and seed
2 an organ system is a group of organs that works together as a biological system to perform one or more function.
3 collenchyma is a tissue straighten by the thickening of cell walls as in the young shoot.
4 cells are the basic building blocks of living organisms. the the human body consists of trillions of cells.
I hope this will help you
Explanation:
Answer of questions
B) Organ system-An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ does a particular job in the body, and is made up of distinct tissues.
A)Dermal tissue -The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.
C)Collenchyma-Collenchyma, in plants, support tissue of living elongated cells with irregular cell walls. Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross section. The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells.
D) Anaerobic respiration-Anaerobic respiration is respiration using electron acceptors other than molecular oxygen. Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain
E) Cells- The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life".
