Important Topics for Class 9 Science Chapter 6 Tissues

Tissue is a group of cells with a similar form and function forming a cellular organizational level that sits in between the cell and organ system hierarchy. These are made up of a collection of specialized cells that execute certain tasks. The combination of the functional groups of tissues forms organs.

Single Cell Protein (SCP)

Single cell protein (SCP) or microbial proteins can be expressed as the dried and dead cells of microorganisms, including yeast, bacteria, fungi, and algae.

Example: How is Single Cell Protein (SCP) produced?

Solution: Single Cell Protein (SCP) can be produced by the following steps:

Selection of suitable strain
Fermentation
Harvesting
Post-harvest treatment
SCP processing for food

Biofortification

Biofortification can be defined as the process that helps in the development of via bioavailable micronutrients present in its edible parts.

Example: Name the three processes of Biofortification.

Solution: The three processes of Biofortification are:

Conventional
Agronomic
Biotechnology

Simple Permanent Tissues

Simple permanent tissue are also referred to as homogenous tissues. They are called Simple Permanent Tissues because they contain a single cell type, often having the same origin, structure, and function.

Simple Permanent Tissues can be further divided into three segments:

Parenchyma
Collenchyma
Sclerenchyma

Connective Tissues

Connective tissues are a group of tissues present in the body that are further responsible to maintain and offer internal support to organs. It is found in abundance in the body.

Connective Tissues can be divided into three major segments:

Loose Connective Tissue
Dense Connective Tissue
Specialised Connective Tissue
