Human reproduction

Reproduction relies on specialised organs and a cycle that prepares the body, month after month, for the possibility of pregnancy.

Learn

Male reproductive system

The testes produce sperm cells and the hormone testosterone. Sperm travel through the sperm duct, mixing with fluids from glands to form semen, which passes out through the penis during ejaculation.

Learn

Female reproductive system

The ovaries release an egg cell roughly once a month. The egg travels down the oviduct (fallopian tube), where fertilisation can occur. If fertilised, the embryo implants in the uterus lining; if not, the lining breaks down.

Learn

The menstrual cycle

The menstrual cycle lasts about 28 days. It includes menstruation (shedding the uterus lining), a rebuilding phase, ovulation (release of an egg around day 14), and a phase where the lining thickens ready for possible implantation.

Case study

Why the school greenhouse failed

A science club grew tomato plants in the school greenhouse. In June the plants grew well: leaves were dark green and the fruit set quickly. In July the club went away for two weeks and left the greenhouse door shut. When they came back, the leaves were curled and pale and most of the fruit had dropped.

The club had a data logger inside. It showed the temperature reached 46 °C on several afternoons and the soil moisture fell close to zero. The club knew photosynthesis needs light, water and carbon dioxide, and that enzymes in a plant work best in a narrow range of temperature. Above that range the enzymes stop working properly.

The club repeated the summer with the door propped open and a water bottle drip on each pot. Temperature peaked at 31 °C and the plants survived.

Written for Good Learning Co.

Reading questions

  1. Name the variable the club changed the second time, and one variable they kept the same.
  2. Explain, using the words photosynthesis and enzymes, why the plants were damaged in July.
  3. Write a conclusion for the club's report, saying how far the evidence supports it.

  • Method and results
