Well, plant and animal cells are what build multicellular organisms. Multicellular organisms have different organs and what not. We need different cells to do different jobs. Otherwise specialization. So basically, we need different cells for our bodies' purposes, and for right parts to function properly.
Because they Evolved and developed that way.
Simple tissues - Made up of the same type of cells. - Covers the surface of internal (e.g. brain) and external (e.g. skin) organs. - The cells are packed tightly together. - Called epithelium in animals and epidermis in plants. - Examples are the muscle tissue in animals and dermal tissue in plants. Complex tissues - Made up of different type of cells. - Inside or between organs and supports and binds other tissues - The cells are thorougly scattered. - Called connectivity tissue in animals and vascular tissue in plants. - Examples are the blood tissue and bone tissues in animals, and the xylem tissue and phloem tissue in plants.
The most common element in plant tissues is Carbon. This is why plants and animals are called carbon-based life forms; because we are made predominately out of carbon.
no

Settles came and farms were made. New plants and animals were brought in. Most of the bison were killed. Some animals moved to other areas.
Because they Evolved and developed that way.

Chlorophyll is used by plants to capture light energy during photosynthesis, plants use photosynthesis to make their food. Animals do not make their own food they get their food ready made so the don't to do photosynthesis or have chlorophyll
plants are made up of tissues
Simple tissues:- Are made up of the same type of cells.- Cover the surface of internal (e.g., brain) and external (e.g., skin) organs.- The cells are packed tightly together.- Are called epithelium in animals and epidermis in plants.- Examples are the muscle tissue in animals and dermal tissue in plants.Complex tissues:- Made up of different type of cells.- Inside or between organs and supports and binds other tissues.- The cells are thorougly scattered.- Called connectivity tissue in animals and vascular tissue in plants.- Examples are the blood tissue and bone tissues in animals and the xylem tissue and phloem tissue in plants.Simple tissues- Made up of the same type of cells.- Covers the surface of internal (e.g. brain) and external (e.g. skin) organs.- The cells are packed tightly together.- Called epithelium in animals and epidermis in plants.- Examples are the muscle tissue in animals and dermal tissue in plants.Complex tissues- Made up of different type of cells.- Inside or between organs and supports and binds other tissues- The cells are thorougly scattered.- Called connectivity tissue in animals and vascular tissue in plants.- Examples are the blood tissue and bone tissues in animals, and the xylem tissue and phloem tissue in plants.

Tissues are made up of different cells which perform similar functions.

An organ is a structure that is composed of 2 or more different kinds of tissues.
