Biology 2

• Photosynthesis - it is process where the plant convert light energy from the sun into chemical energy
• Plant - they make oxygen
• Plant - they perform photosynthesis
• Botany - study of plant
• Botanist - a person studies plant
• Cell wall - give shape to the cell

  -protect cell
• Chloroplast -capture light energy from the sun
• Vacuole - storage of material, nutrient and other substances of the plants
• Multicellular - organism comprised with multiple cell
• Eukaryotic - organism that have three nucleus and membrane bound organelles
• Photosynthetic - capable of performing photosynthesis
• Autotrophs - organism that can produce their own food
• Cell walls are made of cellulose
• Cellulose - complex carbohydrate (polysaccharide)
• Stores starch - complex carbohydrate but restored or reserved
• Cell division - parent cel divides into two or more daughters cell
• Vegerative organs - responsible for growth and survival of the plant
• Roots - responsible for absorbing water and other nutrients from the soil
• Leaves - primary site of photosynthesis
• Stem - give structural support to the plant and transport the nutrients to other part of the plant
• Reproductive organ - responsible for continuation of species through production of seed or spores
• Flower - reproductive organ of the plant
• Fruit - developed ovary of the flower which contains seed
• Cones - reproductive organ of gymnosperms
• Vascular tissue - specialized tissue responsible for transforming nutrients and other mineral through out the plant
• Phloem - transported to other part of the plant ( leaves)
• Xylem - transported to other part of the plant (roots)
• Meristems - capable of producing roots leaves and other parts of the plant
• Cell wall - allows the plant to continue growing
• Totipotency - ability of a single cell to develop into an organism
• Adaptation - changes or adjusted of an organism in order to become more suited in an environment
• Plant adaptation - the plant species evolve some features in order to survive
• Adaptare - greek word means "to fit"
• Where did the plants came from? - aquatic green algae
• Non vascular plants - plants lack of vascular tissue
• Vascular plants - plants that have vascular tissue in transporting water and minerals
• Vascular non seed plants - produced via spores

  -ferms
• Vascular seed plants - reproduced through seeds

  -flowering plants
• Cuticle - waxy layer of a leaf

  -helps the plant to seal the water and prevent water loss
• Stomata - allows the exchanges of the gases

  -Helps to retain water
