cell structure and plant biology

• Photosynthesis - The process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in Glucose
• Plant reproduction

  flower structure

  Pollination

  seed dispersal
• Flower Structure - essential for pollination and seed formation
• Stamen - Male flower
• Pistil - Female flower
• Pollination - the transfer of pollen from the male reproductive organs to the female reproductive organs of a flower
• Seed Dispersal - disperse by the wind, water, animals, or even self dispersal mechanism
• Plant Tissue

  Meristematic Tissue

  Permanent Tissue
• Meristematic Tissue - region of active cell division responsible for plant growth
• Permanent tissue - perform specific functions like support, storage and photosynthesis
• Evolution

  Natural Selection

  Speciation
• Natural Selection - evolve over time through the process of adaption to their environment
• Speciation - the process by which a population of organisms becomes reproductively isolated from other populations

• Types of cells

  Prokaryotic Cell

  Eukaryotic Cell
• Cell Organelles

  Nucleus

  Mitochondria

  Chloroplasts

  Endoplasmic Reticulum

  Golgi Apparatus
• Cell Function

  Respiration

  Photosynthesis

  Cell Division
• Cell Division

  Mitosis

  Molosis
• prokaryotic cells - lack of nucleus, lack of membrane bound organelles
• Eukaryotic Cells - Cells that contain a true nucleus and other membrane-bound organelles
• Nucleus - contains genetic material and controls cellular activities..
• Chloroplasts - found in plant cells and involved photosynthesis converting light energy into chemichal energy.
• Endoplasmic Reticulum

  Rough ER

  Smooth ER
• Rough ER - involves in protein synthesis
• Smooth ER - Synthesizes lipids and detoxifies certain drugs
• Golgi Apparatus - packages proteins and lipids for storage or transport out of the cell vacuoles
• Respiration - involves the breakdown of glucose to produce ATP, occuring in the mitochondria
• ATP stands for Adenosine Triphosphate
• Mitosis - cell division for growth and repair
• Melosis - cell division for sexual reproduction producing gametes with half chromosome number
