You get constipation
What is the main job for the large intestine?
To remove water
What is the filler between the dermal and vascular tissue?
Ground tissue
Upper and lower leaf surfaces are covered by a layer of epidermal tissue, this tissue is made up of cells with a waxy texture called?
Cuticle
What are special openings in the leaf surface?
Stomata
Stomata openings are surrounded and controlled by pairs of what special epidermal cell?

__________ is the control centre of the cell and contains all the genetic information in the form of DNA.
Nucleus
________ is a cancerous tumour that can spread.
Malignant
What grows on trees and bushes, and is tasty to eat?
FRUIT
A plant becomes limp from heat loss and dehydration
WILT
When not enough water is taken out of what is traveling through the large intestine it causes?
Diarrhea
Name the disease in which a cell does not respond to the nucleus and causes decay and the cell loses the power to regulate reproduction
Cancer
what is the process of exchaning oxygen for carbon dioxide
breathing
The outer most layer of a plant
Dermal tissue
What is a benign tumour?
A non-cancerous tumour
Start of a plants life begins with_____?
Seeds
The transportation system that moves water, minerals, and other chemicals around the plant
Vascular tissue
What is the bottom half of a plants systems?
Roots
What stage of mitosis do daughter cells form?
Cytokinesis
what is bile?
a fluid made by the liver, stored in the gallbladder that aids digestion
in which intestine does most digestion occur?
the small intestine
what is the job of the large intestine?
to absorb water from the indigestible food
what system is responsible for breathing?
the respitory system
What are chromosomes?
Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body.
The final stage in cell division, the cytoplasm divides producing identical cells.
Cytokinesis
What is a right atrium
Is one of four chambers of the heart (corner of the right side)
What is a left ventricle
One of the four chambers of the heart (bottom left portion)
What is the left atrium
One of the four chambers of the heart (left posterior of heart)
What is a pulmonary artery
The artery carrying blood from the right ventricle of the heart to the lungs for oxygenation
The _________ system enables motion, and maintains and regulates body temperature.
Muscular
what are the components of the respitory system?
nose, mouth, trachea, bronchi, and lungs
carries oxygen, rich blood away from the heart
arteries
What is mitosis?
Mitosis is a method of cell division in which a cell divides and produces identical copies of itself.
The longest phase of mitosis.
Interphase
What type of tumour does not affect surrounding tissues?
Benign tumour
What type of tumour interferes with the functioning of surrounding cells? (Cancerous cell)
Malignant tumour
When cancerous cells break away from the tumour and spread it is called ______
Metastasis
What is the process by which cancer cells break away from the original tumour and establish another tumour elsewhere in the body?
Metastasis
Part of the plant that humans always eat?
Vegetables
What is the type of diagnoses used when a sample of a tumour is removed in order to study under a microscope?
Biopsy
What is a Petolie?
The stalk of a plant that connects the leaf to the stem.
What type of cancer is commonly caused by sunlight?
Skin cancer
Two identical strands of a replicated chromosome, often referred to as sisters.
Chromatids
The stage of the cell cycle where two daughter cells are formed and chromatids unwind is
Telophase
The stage of the cell cycle where chromosomes are visible and nuclear membrane dissolves is
Prophase
The stage of the cell cycle where the chromosomes line up
Metaphase
The stage of the cell cycle where the chromosomes begin to split
Anaphase
What is the process of plants converting the Sun’s energy into food?
Photosynthesis
This organ is part of the digestive system, makes bile and stores it in the gall bladder. Located in the chest area.
Liver
The path food takes after the stomach. Part of the digestive system and is where bile from the liver is stored. Fat from food is broken down here to later be converted to energy.
Gall bladder
An action a cell takes in order to grow, reproduce, and repair. Occurs in the order of prophase, metaphase, anaphase, and telophase.
Cell division
All cells come from other cells
All living things are made up of cell
The cell is the basic building block/unit of life
Cell theory
Skin cancer abcd
A a semetracal
D diameter
C colour
B border
What is xylem?
Transports water and dissolved minerals upward from roots.
What is phloem?
Transports solutions of sugars and other dissolved nutrients and hormones throughout the plant.
What transports sugar solutions around the plant?
Phloem
What transports minerals and water upwards from the roots?
Xylem
What is dermal tissue?
Specialized to perform a wide variety of functions, and covers all non-woody surfaces of the plant.
What vascular tissue?
Transportation system that moves water, minerals, and other chemicals around the plant.
What is ground tissue?
Has a variety of functions including manufacturing nutrients, storing carbohydrates, and providing storage and support.
What is peristalsis?
Muscle contraction of esophagus
What is chyme?
The state the food is in once it exits the stomach
What is villi?
Tiny fingers in the small intestine which absorb the nutrients and send them throughout the body through the blood stream.
Where is bile stored?
Gall bladder
blood is made up of:
plasma-55% buffy coat -white blood cells -platelets red blood cells
