Study Notes
Plant Systems Overview
- Plants are composed of tissues. Three main types are dermal, ground, and vascular
- Meristematic tissues are actively dividing cells responsible for plant growth. They are located in the meristems in various regions of the plant
- Different types of meristems exist according to location: Apical Meristem, Lateral Meristem, and Intercalary Meristems
- Non-Meristematic or Permanent Tissues are cells that are no longer actively dividing, and have differentiated into Dermal, Ground, and Vascular Tissues
- Dermal tissues protect the plant, covering it with a single layer of cells called the epidermis. Small pores (stomata) within the epidermis are responsible for gas exchange (CO2, O2), water vapor release
- Ground tissues make up most of the plant's interior, responsible for food and water storage, and metabolic processes
- Parenchyma tissue: spherical/elongated, thin primary cell walls, main component of young plant organs, photosynthesis and storage.
- Collenchyma tissue: elongated cells, unevenly thickened primary cell walls, provide mechanical support to stems and leaves.
- Sclerenchyma tissue: dead cells, thick secondary cell walls, support older plant organs and add strength.
- Vascular tissue carries substances throughout the plant
- Xylem transports water and dissolved minerals from roots to other parts of the plant.
- Phloem transports sugars and amino acids from site of production (like leaves) to other areas
- Plant systems include shoot system (stem, branches, leaves) and root system (anchors plant, absorbs water and nutrients)
Plant Organ Systems
- Shoot system: Includes stems, branches, leaves, flowers, and buds
- Root system: Anchors the plant, absorbs water and minerals from soil. It's largely underground
Monocot vs. Dicot
- Monocots: One cotyledon in seeds, parallel leaf veins, scattered vascular bundles (in stem), lack a typical cambium, adventitious root system
- Dicots: Two cotyledons in seeds, net-like leaf veins, vascular bundles arranged in a ring, typical cambium present, usually a taproot system
Plant Parts
- Leaf: Veins (parallel or netlike), blade/lamina
- Leaf Apex, Leaf Base, Petiole, Margin, Midrib, Venules
Plant Circulation
- Vascular tissues (xylem and phloem) transport water, nutrients, and products of photosynthesis throughout the plant
- Xylem moves water and dissolved minerals upwards
- Phloem transports sugars, amino acids, and some ions
Plant Nutrition
- Plants absorb inorganic nutrients and water from the soil, via roots
- The stem transports materials between the roots and other parts of the plant
- Leaves contain chlorophyll to capture light energy for photosynthesis, a process that produces food for the plant
Plant Respiration
- Stomata, small openings in lower epidermis of leaves, allow for exchange of gases (water vapor, oxygen, and carbon dioxide).
- Guard cells regulate opening and closing of stomata
Plant Response to Stimuli
- Tropisms are directional movements in response to stimuli
- Phototropism: Growth response to light
- Geotropism: Growth response to gravity
- Hydrotropism: Growth response to water
- Thigmotropism: Growth response to touch/contact
Plant Reproduction
- Asexual reproduction: Requires one parent, offspring genetically identical to parent
- Sexual reproduction: Two parents, offspring genetically variable, involves fertilization
Plant Flower Anatomy
- Parts of a flower: Sepal, petal, stamen (filament, anther), pistil (stigma, style, ovary), ovule
Plant Pollination
- Pollination: Transfer of pollen (containing male germ cells) from anther of a flower to stigma
- Self-pollination: Pollen transfers between anther to stigma in same flower or different flowers in same plant
- Cross-pollination: Pollen transfers between anthers and stigma in different flowers of the same species
- Pollinators (insects, birds) transfer pollen
Vegetative Propagation
- Methods of asexual reproduction using vegetative parts (stems, roots, leaves)
- Types: Cuttings, Layering, Grafting
Types of Plants
- Angiosperms: Flowering plants with seeds enclosed in ovaries (fruits)
- Gymnosperms: Non-flowering plants with seeds not enclosed in ovaries
- Ferns: Non-flowering plants with spores
