Study Notes
Characteristics of Living Organisms
- Non-living organisms lack characteristics such as growth, reproduction, response to stimuli, metabolism, and homeostasis.
Plant Structure and Function
- Stomata are the primary sites of gas exchange in plants, facilitating the exchange of oxygen and carbon dioxide.
Nervous System
- The primary function of the nervous system in the human body is to control and coordinate body functions, interpret and respond to sensory information, and facilitate thought and movement.
Cell Structure
- Prokaryotic cells are characterized by the absence of a true nucleus and membrane-bound organelles.
Human Reproduction
- Sertoli cells in human reproduction provide a supportive environment for the development of sperm cells, facilitating the process of spermatogenesis.
- The hormone responsible for stimulating ovulation in the female reproductive system is luteinizing hormone (LH).
- Fertilization in humans typically occurs in the fallopian tubes.
Spermatogenesis
- Spermiogenesis is the process involving the formation of mature spermatozoa from spermatogonia.
