Answer:

The answer is TRUE. Most cnidarians have two layers of cells that are organized into tissues: Epidermis and Gastrodermis.

Explanation:

Cnidarians' basic body organization is simple: It is a hollow structure composed of two cellular layers:

epidermis, which is the external layer,
gastrodermis which is the internal layer, composed by lining cells in the gastrovascular cavity.

Between these two there is the mesoglea that varies from a thin, non-cellular membrane to a mucous, fibrous, thick membrane with amebocytes.

Epidermis and gastrodermis originate from two embryonic tissues, the ectoderm, and the endoderm.

The epidermis is formed of five types of cells with different functions: epitheliomuscular, interstitial, cnidoblasts, secretors, and sensorial.

The gastrodermis is composed of nutritive cells, glandular enzymatic cells, secretory cells, and sensorial cells.

Answer:

Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.

Explanation:

In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.
