tekilochka [14]

Answer:

can ,synthesize specific proteins

Explanation:

Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.

They are transported in the circulatory system of the body

The action of hormones can be seen after the hormone has bound to its specific receptor found inside the cell.

For instance, steroid hormone and the thyroid hormones can pass through the plasma membrane to their receptors inside the cells.

When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.

Answer:

Mitochondria:

An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. Also known as the 'powerhouse of the cell.'

Cell wall:

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Nucleus:

The positively charged central core of an atom, consisting of protons and neutrons and containing nearly all of the cell's mass.

Golgi bodies:

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

ER (Endoplasmic Reticulum):

A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough.

Cell Membrane:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Ribosomes:

A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.

Cytoplasm:

The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.

Hope this helps!

zaharov [31]

Bryophytes are also called NON VASCULAR plants.
Bryophytes are a group of small and green plants, which are made up majorly of hornsworth, liverwort and mosses. They can be found on land or in aquatic environment. These plants do not produce flowers, therefore they are always described as seedless.
