What is a cell?
A membrane enclosed space that can carry out life
What makes a plant cell different than a bacteria cell?
Plant cells are eukaryotic - their DNA is in a nucleus
Bacteria cells are prokaryotic - their DNA is not in a nucleus
What makes a plant cell different than an animal cell?
Enclosed by a membrane
Has DNA in a nucleus
Large Central Vacuole
No cell wall
No large central vacuole
How do plants keep their structure?
Cell Wall - outermost layer of a plant cell that gives structure to the cell - made of fiber
Turgor Pressure - Outward force of the central vacuole on the inside of the cell wall
Vacuole is a large structure that stores water in a plant cell
If the plant doesn't have enough water, the plant will wilt
How do plants get energy?
Photosynthesis - process that converts light energy into chemical energy (food/sugar)
Light + CO2(carbon dioxide) + H2O(water) > C6H12O6(glucose) + O2(oxygen)
What organelle helps plants get energy?
Chloroplast - the organelle where photosynthesis takes place
What makes a plant green?
Chlorophyll - the pigment in chloroplast that absorbs light energy
What are some plant structures you can identify?
Roots - Allow plants to take in water and other nutrients from the soil
Stem - Supports the plant's height
Leaves - Give a broad surface to capture light
Flower - Attracts pollinators, holds reproductive organs that allow plants to make seeds
Xylem - pipe that carries water to all parts of the plant
Phloem - pipe that carries food to all parts of the plant
How does a plant reproduce?
Plants can reproduce sexually and asexually
Some plants reproduce sexually by producing seeds
Pistil - female reproductive parts
Stamen - male reproductive part
Seed - a young plant and food contained in a protective seed coat
Some plants reproduce asexually through budding, regeneration...vegetative propogation
