Lesson 2: Tissue And Cell Modification Flashcards
Give the functions on the parts of plant flower,leaf, fruit,stem,root. upper is shoot system down is root system
•helps in reproduction
•perfroms photosynthesis
•protects the seeds
•supports the plant
•absorb water and minerals
What is called when cells are capable of cell division
Meristematic
What is called when mature cells are incapable of cell division
Permanent
Tissue composed of a single cell type examples are
Simple
•epidermis
•parenchyma
•collenchyma
•sclerenchyma
•chlorenchyma
Tissue composed of more than one cell type are?
Complex
•xylem
•phloem
•xylem vesicles
•sieve tubules
•tracheoids
•companion cells
Outermost cell layer protective role
Epidermis
Stems,roots and nutrient storage
Parenchyma
Shoots and leaves mechanical strength and flexibility
Collenchyma
Mechanical strength water condition
Sclerenchyma
Support the plant transport water and dissolved salts from root to stems and leaves
Xylem
Transport organic nutrients produced during photosynthesis
Phloem
Commonly seen outside the body coverings or as linings of organ cavities consists of tightly packed cells that form a continuous layer it provides protection and covers surface and lines body cavities it also acts as barriers from pathogens mechanical injuries and fluid loss
Epithelial tissue
Flat like
Squamous
Square in side view
Cuboidal
Rectangular side view
Columnar
Secrets a product a gland that can be a single epithelial cell or contain many cells
Grand epithelium
The most abundant and widely distributed tissue and complex animals
Connective tissue
A certain fibroblasts and is separated by a jelly-like matrix
Fibrous
Made up of plasma contains water salts and dissolved proteins
Blood cells
These are composed of long cells called muscular fiber account for movement of body parts
Muscle tissue
Attached to the bone by tendons and creates movement when it contracts voluntary muscle
Skeletal muscle
Made up of neurons which are specialized signaling the cells and supporting cells called neuroglia
Nervous tissue
Whip-like structure that extends from the cell body it push the cell to a particular propylene motion
Flagella
Hairlike protrusionsthat cover most of the parts as they move to sell in vibratory muscle it may motile or nonmotile
Cilia
Are tiny finger like structures is covered by a single layer of epithelial cells and supplied with blood by capillaries
Microvilli
A temporary arm like projection of a eukaryotic cell membrane primarily consists of actin filaments and may also contain factual and intermediate filaments
Pseudopodia
