Biology: Tissue Types

Tissues

Definition

A group of similar cells that perform a specific function together.

Types of Tissues

• Epithelial Tissue: forms the lining of organs, glands, and body surfaces
  • Functions: protection, absorption, secretion, and sensation
• Connective Tissue: provides support, structure, and connectivity to the body
  • Functions: connecting, supporting, and protecting organs and tissues
• Muscle Tissue: responsible for movement and contraction
  • Functions: movement, contraction, and relaxation
• Nervous Tissue: responsible for transmission and processing of information
  • Functions: transmission, processing, and integration of information

Characteristics of Tissues

• Specialization: each type of tissue has unique characteristics and functions
• Organization: tissues are organized into organs and systems
• Coordination: tissues work together to maintain homeostasis

Flower

Definition

The reproductive structure of plants, responsible for producing seeds and fruits.

Parts of a Flower

• Sepals: green, leaf-like structures that protect the flower bud
• Petals: colorful, attractive structures that attract pollinators
• Stamen: male reproductive organs, consisting of filaments and anthers
• Pistil: female reproductive organ, consisting of stigma, style, and ovary
• Receptacle: the base of the flower that supports the other parts

Functions of a Flower

• Reproduction: produces seeds and fruits through fertilization
• Attracting Pollinators: attracts pollinators, such as bees and butterflies, to facilitate reproduction
• Protection: protects the reproductive organs from damage and disease
