List the importance of plants
Provide food Provide shelter Control flood and erosion Cycle nitrogen Source of energy Replenish O2 Removal of CO2
What are the characteristics of living organisms
Have cells and are organized Acquire energy and material Grow and develop Reproduce Respond to stimuli Adapt to their environment
What is the organization of cells
Organelles, cells, tissues, organs, organism, population, community, ecosystem
Characteristics of plants
Multicellular eukaryotes
Use chloroplast to carry out photosynthesis
Store energy or food as starch
Have cell walls made of cellulose
Multi cellular embryos that develop with female sex organs
Life cycle alternating between haploid and diploid
