Gas exchange
Defense
What are the 3 kinds of plant ground tissues?
Parenchyma
Collenchyma
Sclerenchyma
What kind of tissue makes up the bulk of a plant?
Ground tissue
Describe the structure, function, and location of the parenchyma
Thin walled, living, large central ventriole
Storage, photosynthesis, wound healing, secretion
Softer tissues - leaves, stems, roots, fruits
Describe the structure, function, and location of the collenchyma
Unevenly thickened, living, elongated
Beneath epidermis
e.g. celery stalk - provides mechanical support
Describe the structure, function, and location of the sclerenchyma
Thick primary cellulose cell wall, lignin secondary cell wall, non-living
Forms fibres and sclereids
Rigid support
Describe skeletal muscle tissue
Striated
Attached to bones via tendons
Long cylindrical cells
Multinucleated
Describe cardiac muscle tissue
Striated
Branched
Cylindrical cells
Single or binucleated
Describe smooth muscle tissue
Non-striated
Thick and thin filaments not in an orderly structure
Spindle shaped cells
Name the 3 kinds of connective tissue
Proper
Fluid
Supportive
What are the 2 kinds of proper connective tissues, with examples?
Dense - elastic, dense regular
Loose - adipose, reticular
What cells secrete ECM?
Fibroblast
What cells store lipids as droplets?
Adipocytes
What makes up the animal ground substance?
Glycosaminoglycans
