science notes

lesson 1,2,&3

Autotrophs can make their own food though photosynthesis
multicellular cells are organized into tissues
Eukaryotic cells have cell walls, chloroplast and a large vacuole
cuticle plants must take in water and their nutrients from their surroundings
absorbing some simply absorb these into their bodies and pass them from cell to cell
vascular tissue though which water, nutrients, and food travels
asexually by way of tubers, runners, and plantlets
sexually fertilization occurs when a egg cell unities with a sperm cell
zygote the fertilized egg is called a zygote like flowers, fruits, and cones
vascular and nonvascular plants can be divided into 2 major groups
nonvascular plants DO NOT have a tubular system(root system) for transporting food and water they grow low to the ground and usually in shady, damp areas
vascular plants have well developed vascular tissue to trans port and move materials throughout the plant. this tissue also provides strength, stability, and support to these plants are able to grow tall
sporophyte stage is when the plants produces spores
gametophyte then this stage produces sperm and egg cells and then the cycle starts all over again
photosynthesis is the process by which plants make food
chloroplast this takes place in the chloroplast inside the cells.
chlorophyll the chlorophyll is inside the chloroplast it absorbs green pigment in the plants that make them green
