According to Reece et al. (2015)‚ animals can be described as organisms that are multicellular‚ heterotrophic eukaryotes that have tissues made from embryos. The difference between plants and animals are from their source of nutrients. Plants get their food by making them through a process called photosynthesis‚ which makes plants an autotroph. Animals‚ on the other hand‚ get their food by consuming other organisms and ingesting them‚ which makes them a heterotroph. Besides that‚ there are also variations

smallest life organisms around. There are 2 types of bacteria. 1 is Archbacteria. 2. Eubacteria. Protists Protists are organisms in the kingdom Protista. The organisms are eukaryotes which means they are made up of single or multiple cells which all contain a nucleus and a membrane. protists are a cool group of eukaryotes that cannot be classified as animals‚ plants‚ or fungi. Organisms in the Protista kingdom include amoebae‚ euglena and slime molds. Protist move throuout the slime molds and

Students now want to determine how the use of rainwater or bottled water affects the growth of this plant. Which conditions should be used for optimal growth as the two water types are tested?

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

Metabolism is the mechanism that creates order and complexity from chaos‚ by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication‚ ii. Inheritance‚ iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits
