What are the main types of plant tissues?

Simple (parenchyma, collenchyma, sclerenchyma) and complex (xylem, phloem) types.

What are the categories of animal tissues?

Epithelial, connective, muscular, and nervous tissues.

Aid in water and food conduction in plants.

Dendrites, cell body, and axon.

Mitosis replicates cells, while meiosis halves chromosome numbers.

Cells combine to create tissues in organisms, with plant tissues including meristematic and permanent types, while animal tissues are divided into epithelial, connective, muscular, and nervous categories.
An in-depth exploration of tissues reveals the functions and structures of various types, such as xylem and phloem aiding in plant food and water conduction, and neurons transmitting signals through synapses with the help of neurotransmitters and the myelin sheath.

Ankitha Sharma, a biology teacher, presents a one-shot video for ninth-grade students on tissues.
Ankitha motivates students with a quote on success and encourages them to keep studying hard for their upcoming exams.
She acknowledges students' participation in answering a homework question about DNA.
Ankitha introduces the topic of tissues, explaining that cells coming together form tissues with a specific function.
She delves into plant tissues, discussing meristematic tissues that continuously divide and permanent tissues that do not.
Plant tissues include simple (parenchyma, collenchyma, sclerenchyma) and complex (xylem, phloem) types.
The complex plant tissues, xylem and phloem, aid in water and food conduction in plants.
Moving on to animal tissues, Ankitha categorizes them into epithelial, connective, muscular, and nervous tissues.
Epithelial tissues include simple squamous, cuboidal, columnar, pseudostratified columnar, and stratified squamous epithelium.
Connective tissues encompass ligaments, tendons, adipose tissue, blood, bones, cartilage, and the areolar connective tissue.

Involuntary features of the body include the inability to control the heartbeat and smooth muscles found in internal organs, which are spindle-shaped with a nucleus.
Neurons consist of three major parts: dendrites, cell body, and axon, which transmit signals through synapses where neurotransmitters interchange, facilitating impulse transfer.
The myelin sheath, produced by Schwann cells, protects signals from damage, with gaps called nodes of Ranvier present, aiding in signal transmission.
Mitosis involves DNA replication for exact cell division, while meiosis halves chromosome numbers in gametes, with reduction and equational divisions occurring in two stages.
Connective tissues like blood and bone are discussed, along with complex permanent tissues like phloem, and examples of tissues such as stratified squamous epithelium are provided.
