What are the two main types of plant tissues?

Meristematic and permanent tissues.

What are the characteristics of parenchyma tissues?

Intercellular spaces and living protoplasm.

In climbers, providing flexibility and support.

Providing mechanical support and seed covering.

Preventing water loss and invasion, facilitating gas exchange.

Meristematic tissues in plants continuously divide and are crucial for growth, including apical, lateral, and intercalary meristems.
Protective tissues in plants like leaf epidermis and root epidermis have specific functions such as preventing water loss, aiding in gas exchange, and absorbing water, showcasing the diverse roles of plant tissues.

The class is focused on discussing tissues in a one-hour session.
The teacher, Anita, welcomes everyone and clarifies it's not her birthday.
The class covers plant tissues, divided into meristematic and permanent tissues.
Meristematic tissues continuously divide and play a crucial role in plant growth.
Meristematic tissues include apical, lateral, and intercalary meristems.
Permanent tissues are derived from meristematic tissues through cell differentiation.
Simple permanent tissues have similar cells, providing structural support and storage.
Parenchyma, a type of simple permanent tissue, has characteristics like intercellular spaces and living protoplasm.
Parenchyma includes chlorenchyma with chloroplasts for photosynthesis and aerenchyma with air cavities for floating.
The class emphasizes the importance of understanding the characteristics and functions of different plant tissues.

Colon Kima is characterized by thick walls and corners, long living cells with thick cell walls and regular thickening, and minimal intercellular space.
Colon Kima is found in climbers, providing flexibility and mechanical support to plants, especially tendrils.
Colon Kima's unique feature is its thick corners, crucial for plant flexibility.
Scaren Kima consists of dead cells with thick lignified cell walls and a narrow lumen, found in hard seed structures and vascular bundles, providing mechanical support and seed covering.
Lignin in Scaren Kima cells creates a cemented structure, making them impermeable.
Protective tissues like leaf epidermis have a waxy cuticle preventing water loss and invasion, with stomata facilitating gas exchange.
Root epidermis contains root hairs aiding water absorption.
Cork cells in protective tissues have suberin, forming a tough covering that reduces water and gas exchange.
Xylem transports water and minerals unidirectionally from roots to plant parts, with components like tracheids, vessels, parenchyma, and fibers.
Phloem transports food bidirectionally, with sieve tubes, companion cells, parenchyma, and fibers as components.

Cilia are hair-like structures present in the oviduct and trachea, aiding in movement and secretion.
Glandular epithelium secretes substances like enzymes, found in the stomach and intestine.
Villi in the small intestine aid in absorption, while cilia assist in substance movement.
Skeletal muscles are voluntary, long cylindrical muscles attached to the skeleton for movement.
Smooth muscles are involuntary, spindle-shaped muscles found in the esophagus and intestines.
Cardiac muscles are only in the heart, working continuously to pump blood.
Connective tissues like loose connective tissue, adipose tissue, and bone provide support and structure.
Bones, cartilage, tendons, and ligaments are dense connective tissues with specific functions.
Blood is a fluid connective tissue with cellular components like RBCs, WBCs, and platelets, and non-cellular components like plasma.
Nervous tissue in the brain and spinal cord is made up of neurons with dendrites, myelin sheath, and axons for transmitting nerve impulses.

50:34

Neurons consist of dendrites for receiving information, a cell body or cyton, an axon for transmitting information, and an axon terminal where electrical impulses pass between neurons through a synapse.
Lymph is a fluid derived from blood capillaries, forming tissue fluid without red blood cells or platelets but containing white blood cells and plasma, constituting the lymphatic system.
Ligaments join bones together, providing elasticity and aiding movement, while cartilage cushions bones, and tissues require blood for nutrients, oxygen, and waste removal.
