Unit 10: Plants and Body Systems

9th grade bio review

Ather

part of the stamen that contains pollen

Circulatory function

Transport materials to and from cells

circulatory system

consists of the heart, blood vessels, and blood

cross-pollination

a reproductive process in which pollen from one plant is transferred to the stigma of another plant

digestive functions

processes and digests food, absorbs and conserves water, absorbs nutrients, stores energy reserves

digestive system

mouth, pharynx, esophagus, stomach, intestines, liver, gallbladder, pancreas

endocrine function

controls growth, development, and metabolism; maintains homeostasis

endocrine system

consists of hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid glands, thymus, adrenal glands, and pancreas

excertory system

kidney, uterus, urinary bladder, and urethra

Excretory function

eliminates waste products; helps maintain homeostasis

filament

Supports the anther

flower

reproductive part of the plant and makes seeds

fruit

protects the seeds and helps with seed dispersal

Gravitropism

A growth response to gravity

Hydrotropism

a plants growth response to water; plant grows towards the water

immune function

the body's normal ability to fight infection and illness with antibodies and lymphocytes

immune system

consists of cells that protect the body against viruses, bacteria, and other intruders

Integumentary Functions

protects against environmental hazards, helps regulate body temperature, provides sensory information

integumentary system

Consists of the skin, mucous membranes, hair, and nail

leaf

The major sites of photosynthesis in most plants.

Muscular function

works with skeletal system to produce voluntary movement; helps to circulate blood and move food through the digestive system

Muscular System

Consists of skeletal muscles, tendons that connect muscles to bones, and ligaments that attach bones together to form joint

nervous function

Conduct impulses for coordination, regulation, integration, and sensory reception

nervous system

brain, spinal cord, nerves

nonvascular plants

Plants that lack a well-developed system of tubes for transporting water and other materials

Ovary

A flower structure that encloses and protects ovules and seeds as they develop.

Phleom

Carries food and other material both up and down the plant

Phtotropism

growth towards light, normally positive towards light

Pistil (female)

the female reproductive organ of a flower that can be fertilized by pollen

plant asexual reproduction

reproduction without the fusion of sex cells, resulting identical offspring and parent

plant sexual reproduction

reproduction that involves two parents and produces offspring that are different from either parent

pollinator

an insect that carries pollen from one flower to another

reproduction function

to produce sex cells (meiosis) that function in creating new humans in fertilization (sex)

Reproduction system

for males consist of testis,penis while for female ovares, filmina, uterus and vagina

Respiratory function

Provides oxygen needed for cellular respiration and removes excess carbon dioxide from the body

Respitory system

lungs, trachea and diaphragm

root

absorb nutrients and water, anchors plant

self-pollination

the pollination of a flower by pollen from the same flower or from another flower on the same plant.

Skeletal Functions

provides support and protection for other tissues, stores calcium and other minerals, forms blood cells

skeletal system

consists of bones, cartilages, ligaments, and joints

Stamen (male)

male reproductive organ of a flower that produces pollen

stem

supporting structure that connects roots and leaves and carries water and nutrients between them

stigma

The receptive surface of the female organ of a flower that receives the pollen.

Stomata

A microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant.

Style

The stalk of a flower's carpel, with the ovary at the base and the stigma at the top.

Thimotropism

A growth response to touch

Tropism

A growth response of a plant toward or away from a stimulus

vascular plants

Plants that have tubes inside of them to transport liquid.

what type of cells regulate the stomata?

guard cells

Xylem

Transports water and nutrients to leaves
