There are four types of tissues in the organism (epithelial, muscular, connective, and nervous). Tissues are composed of cells and extracellular matrix.

<h3>What are tissues composed of?</h3>

Tissues are cells organized and associated, accomplishing different functions in the organism.

There are four types of tissues: epithelial, muscular, connective, and nervous.

All of them are composed of the same components that might vary according to the tissue and its functions.

  • Cells

Cells are the main component of tissues. Their shape, size, organization, and closeness vary from tissue to tissue.

  • Extracellular matrix

The extracellular matrix is the space between cells. It varies in size, state,  and composition depending on the tissue.

It contains proteins, water, salts, and other macromolecules. This composition also varies.

Among their many different functions, we can mention hydration, mechanical pressure resistance, reproduction and cell differentiation, motility, substances diffusion, communication between cells, and damaged tissue repairing, among others.

In addition to cells, the extracellular matrix compose tissues.

Why are pigments such as chlorophyll needed for photosynthesis
Vlad [161]

Answer:

The chlorophyll pigment have photosystem 680/ PS I which captures the sunlight. Then the pigments gets excited and photosynthesis starts. Without chlorophyll photosynthesis can't happen.

Explanation:

Photosynthesis occurs in the chlorophyll pigment of the plant. They have the capacity to trap light energy and convert its energy to form glucose and oxygen.  

The chlorophyll is a double layer membrane structure. In it two photosystems works i.e. photosystem I and photosystem II. In the photosystem I light is trapped.  

In the chlorophyll thylakoids are present which have photosystem 680. It captures the photons coming from the sun. The photons are the light of different wavelengths which are absorbed by plants.  

The photon have more energy, and when it comes in contact with PS 680, the pigments get excited. Then they release high energy electrons which helps to form ATP, NADPH. Because it is a light dependent reaction.

Glucose and oxygen are formed in the stroma as it does not require light. It is a light independent reaction.

Therefore, chlorophyll is first require to capture photons coming from sun.

3)What are some examples of specialized cells
finlep [7]

Answer:

3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.

Explanation:

4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.
