* Plants live in two difference environments at the same time: * * air - stem and leaves‚ surrounded by air and where light‚ CO2‚ and oxygen. * soil - roots‚ supplies water and nutrients. * Each part of the plant has a specific function: * * leaves - carry out photosynthesis. * roots - anchor the plant & absorb water and soil nutrients. * stems - support the leaves and transport materials to other plant parts. * What does the plant

bark and wood). In spring‚ the cambium begins dividing. This creates new tissue and increases the diameter of the tree at two places: 1. Outside the cambium. The outer cells become part of the phloem. The phloem carries food produced in the leaves to the branches‚ trunk‚ and roots. Some of the phloem dies each year and becomes part of the outer bark. 2. Inside the cambium. The inner cells become part of the xylem. These cells contribute most of a tree’s growth in diameter. The xylem carries

Internal Structure Of A Plant PLANT CELL STRUCTURE Plant cells are classed as eukaryotes organisms‚ because they have a membrane enclosed nuclei and organelles. Here is a diagram of a plant cell;  Cytoplasm Most chemical reactions take place here. It helps the cell maintain it’s shape. Nucleus The nucleus has two main roles. Firstly it contains all the cells genetic information. Secondly it coordinates the cell’s activities‚ which include growth‚ intermediary metabolism‚ protein synthesis

EXERCISE 1: A BEGINNER’S GUIDE TO THE STUDY OF PLANT STRUCTURE Adonay‚ Jessa and Velos‚ Mary Angelie Biology Program‚ Sciences Cluster University of the Philippines Cebu Lahug‚ Cebu City‚ Philippines ABSTRACT Plants have essential requirements to survive like all other living being. Roots‚ stems‚ leaves‚ and flower serve to help them acquire or provide for these requirements. Plants exposed to different climates pose different arrangement in the structures’ tissues.

Structure & Function of Plants Review: Plant Structure‚ Growth‚ and Development I 1. How does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant? 2. When you eat the following‚ what plant structure are you consuming? Brussels sprouts‚ celery sticks‚ onions‚ and carrot sticks. 3. Characterize the role of each of the three tissue systems in a leaf. 4. Describe at least three specializations in plant organs and

CELL STRUCTURE CELL THEORY: Structural and functional unit of all living things New cells arise from already existing cells Cells contain information that instructs growth. This information can be passed onto new cells. MICROSCOPES: There are two main types of microscopes: Light and Electron Electron Micrographs- shown in colour LIGHT ELECTRON Uses beam of light Magnification = x1500 Resolution = 200 nm Wide range of specimens can be used Samples are fairly quick + easy to prepare

Monocot roots have a vascular cylinder of xylem and phloem that surrounds a central pith. 5. a. Where is the starch located in carrot root? cortex b.
